Karst processes taking place on the shores of reservoirs and associated phenomena are of great interest when studying the engineering geological situation of the region chosen for dam construction. The processes are important from the viewpoint of filtration leakage control and the forecast of the shore-retrogressing process and land stability by construction of industrial and civil projects.

The problem under consideration is the dynamics of karst massif formation under reservoir conditions. Three stages are singled out. Interaction between the processes of solution and suffosional removal of the filling material of karst cavities is shown. The authors describe the characteristic features of the processes taking place in sulphate and carbonate rocks. To evaluate the time of collapse and volume of shore retreat special formulae are used.

Principes theoriques du pronostic des conditions geotechniques sur les rivages des reservoirs karstiques


Les processus karstiques qui se passent sur les rivages des réservoirs d'eau et les phénomènes qu'ils provoquent out un grand intérêt quand on étudie la construction géologique du territoire où l'on construit un barrage, quand on révèle la fuite d'eau de filtration. Ces processus doivent être pris en considération pour le pronostic de la destruction du rivage et de la stabilité du sol en cas de constructions industrielles et civiles.

Il s'agit dans le rapport du dynamisme de la modification du massif riverain karstifié. On distingue trois stades. On examine la corrélation des processus de solution et de suffosion des cavités karstiques. On caractérise des processus qui ont lieu dans les roches sulphatées et carbonatées. On cite des formules pour calculer le temps de la formation de l'éboulement et le volume de la destruction du rivage.
