EDITORS: Marinos-P.G; Koukis-G.C; et-al SOURCE: Engineering-geology-and-the-environment-Proc-symposium-Athens-1997-Vol3. 1997; 2885-2890 ABSTRACT: The paper presents the results of calculations performed to analyze the processes of stress concentration on heterogeneities and to estimate the stability of the heterogeneous rock massif at man-made actions. The mechanical model of solid body with heterogeneities was used for the simulation. Two problems are described. The first one is the analysis of stress concentration process on the fault in Khibiny massif on Kola Peninsula. The shift along this fault caused the man-made earthquake in 1989. The mechanism of this earthquake is discussed. The second problem is the analysis of the stress concentration in the rock foundation of arch dam on Inguri river during the cyclic change of the storage lake level. The cyclic load regimes under which the accumulation of tensile stresses on rock mass heterogeneities occurs are considered.

EDITORS: Marinos-P.G; Koukis-G.C; et-al SOURCE: Engineering-geology-and-the-environment-Proc-symposium-Athens-1997-Vol3. 1997; 2757-2762 ABSTRACT: The human-induced factors of hazardous slope gravitational processes with negative geoenvironmental consequences are considered on the basis of analysis of the construction and exploitation of the unique hydroelectric power plant at the Inguri River (Western Georgia). The recommendations on the assurance of geoenvironmental safety in the specific conditions of mountain country are given. ACCESSION NUMBER: 0350616 TITLE: Engineering geological analysis of control observations in the foundation of the Inguri arch dam. AUTHOR: Kereselidze-S.B.; Remenyak-M.B. EDITORS: Marinos-P.G; Koukis-G.C; et-al SOURCE: Engineering-geology-and-the-environment-Proc-symposium-Athens-1997-Vol3. 1997; 2753-2755 ABSTRACT: The paper deals with the unique Inguri dam located on the Great Caucasus Southern Slope. It presents an arch with double crookedness; its height is 271.5 m, the crest of the dam being 758 m long; the foundation of the dam is composed of Upper Cretaceous carbonated rocks. Is outlined the general picture of the spreading of the systems of joints with some regularities of the filtration stream formation. Counterfiltration measures are also set forth. About 7 thousand instruments have been installed within the dam body for monitoring the current processes. Analysis of the data revealed appreciable effect upon the geological environment - considerable change of the stress-deformation state and the filtration regime. During the filling of the reservoir the rise of the dam foundation was detected for the first time. In 1986 an abrupt drain off resulted in rock-block dips that were 10 times as great as those during the previous period, though the next year the subsequent filling made it evident that the rock massif was responding in quite a different mode. Within the cement screen appeared a new system of joints and it turned out impossible to seal them with cement. 'Dam-foundation' model test showed expansion of the anomalous zone of tensile stresses, within which only plastic matters should be applied. ACCESSION NUMBER: 0350615 TITLE: Certain problems of interpreting the data of on-site observations in the foundation of the Inguri arch dam. AUTHOR: Remenyak-M.B. SOURCE: Hydrotechnical-Construction. 1997; 30(12): 712-715 ORIGINAL SOURCE: translated from: Gidrotekhnicheskoe Stroitel'stvo 1996 12 (11-15) ABSTRACT: The Inguri arch dam is one of the largest hydraulic structures in the world. Such structures have a considerable effect on the geologic environment. The foundations of high dams, as a rule, develop active technogenic and natural geodynamic processes substantially altering their stress-strain state and seepage regime. The essence of the developing processes vague; it is difficult to obtain quantitative parameters, since there is no uniformity even in their qualitative descriptions on various dams under various geologic-structural conditions. The development of technogenic and natural processes is related not only to the size of the structure itself; it is determined mainly by the characteristics of the geologic environment. Therefore it is very important to know the regularities of the mutual arrangement of individual engineering-geologic elements and their capacity to react in one way or another to the action of the mass of the structure, reservoir, and formation of the seepage flow. When organizing any works it is necessary to examine jointly the structure-foundation or structure-geologic environment system, without separating one from the other, and in the ideal case to make a comprehensive analysis of the effect of the structures on the environment and of the environment on the hydraulic structures. ACCESSION NUMBER: 0278804 TITLE: State of the arch dam of the Inguri hydroelectric station and its foundation: based on 1995 inspection data. AUTHOR: Gol'-din-A.L.; Mgalobelov-Yu.B.; Savich-A.I.; Sudakov-V.B.; Braitsev-V.V. SOURCE: Hydrotechnical-Construction. 1997; 30(9): 556-560 ORIGINAL SOURCE: translated from: Gidrolekhricheskoe Stroitel'stvo 1996 9 (39-42) ABSTRACT: Results of monitoring and inspection programmes on the double-curvature arch dam and its foundations at the Inguri hydroelectric station are presented. Monitoring and measurement equipment was installed in the body and foundation of the dam for onsite observations of the state of the dam. The state of the dam is described and recommendations are given for repair and maintenance work. The safety and reliability of the dam is discussed. ACCESSION NUMBER: 0271768 TITLE: Regrouting joints and its effect on the stress-strain state of the Inguri Arch Dam. AUTHOR: Ashikhmen,-V.-A.; Pronina,-L.-E. SOURCE: Hydrotechnical-Construction. 1995. 28(10), pp 569-580. ORIGINAL SOURCE: translated from: Gidrotekhnicheskoe Stroitel'stvo , (10), 1994, pp 1-9 ABSTRACT: The Inguri hydroelectric power station was completed in 1986. This article discusses in detail the regrouting works, technology, and equipment used in the complete regrouting of the entire arch dam to improve its stress-strain state. Success of the operation was possible due to the development and application of new technologies including high penetrability grouts and grouts with regulated time of loss of fluidity. The stress-strain history of the dam, mathematical modelling and on-site observations, and the effects of grouting are also described. -J.M.McLaughlin ACCESSION NUMBER: (1153338); 96T-4238 TITLE: Criteria for selecting and assigning optimal temperatures for grouting joints. AUTHOR: Zhivoderov,-V.-N. SOURCE: Hydrotechnical-Construction. 1993. 27(9), pp 532-539. ABSTRACT: In dam construction practice in the Russian Federation, 13 high dams were constructed since 1960 with grouted joints, on two of which (Boguchany and Bureya hydroelectric stations) works are presently continuing. Of the achievements of our school of sealing high dams with grout, it is necessary to note: of the 22 dams with a height of more than 200 m constructed in the world during 65 years, four dams (approx= 17%) were constructed in the Russian Federation and countries of the Commonwealth of Independent States (CIS) during the past 20 years. These are the Chirkey (height H = 232.5 m) and Inguri (H = 271.5 m) arch dams, the Toktogul gravity dam (H = 215 m), and Sayano-Shushenskoe gravity-arch dam (H = 245 m). When grouting column and section (radial) joints of high and superhigh dams, for best sealing it is important to select correctly the temperatures determrining the optimal time of injecting the cement group. It is expedient to assign the optimal temperature of sealing vertical joints between columns and sections of the dam not only during construction of the structure but also at its design stage. Therefore the data presented are of interest for civil engineers and designers. -from Authors ACCESSION NUMBER: (1065218); 94T-5211
AUTHOR: Remenyak,-M.-V. SOURCE: Hydrotechnical-Construction. 1993. 26(11), pp 728-733. ORIGINAL SOURCE: translated from: Gidroteknicheskoe Stroitel'stvo, 11, 1992, pp 24-28 ABSTRACT: Comprehensive full-scale observations conducted over the course of 13 years of monitoring in the base of the Inguri arch dam make it possible to evaluate the processes of filtration deformation under the action of the changing hydraulic stress-strain state of the rock mass. This relationship is most fully manifested in the process of annual deep draw-downs of the reservoir. At that time, the rock base experiences the greatest filtration deformation, which is confined to large stratification cracks and zones of intersection of cracks of other systems with clay filler. Further observations and investigations are necessary to develop engineering measures that will alleviate or eliminate the negative action of filtration deformation on the arch dam's operation. -from Author ACCESSION NUMBER: (1016785); 94K-01180 TITLE: Protection of the sea shore of Georgia against destruction. AUTHOR: Zenkovich,-V.-P. SOURCE: Izvestiya,-Akademiya-Nauk-SSSR,-Seriya-Geograficheskaya. 1990. 6, pp 47-51. ABSTRACT: The main factors in the destruction of the sea shores of Georgia are discussed. They include inappropriate sea defence measures, the removal of material for building, the arrangement of harbour defences and the construction of a dam for hydroelectric power on the river Inguri. A new method of coastal protection is described. It is based on the restoration of beaches using river alluvium from underwater canyons and material from quarries. The action of waves on the restored beaches creates a new natural equilibrium which protects the coastline from further erosion. -P.Cooke ACCESSION NUMBER: (0881130); 91H-08474
