摘要

Continuing research of stress unloading in open trenches, and also in large underground excavations has demonstrated the need to account for the development of natural and techno-natural processes over time. Unique data on the change in the velocities of elastic waves and the stress state of a mass at depths of the order of 100-300 m in the foundation bed of the high-head dam for the Inguri hydroelectric plant, which were obtained under the guidance of Doctor of Physical and Mathematical Sciences, Academician of the Russian Academy of Natural Sciences A. I. Savich. have been particularly impressive. The problem of assessing the risk of development of natural and techno-natural processes has received serious attention. According to the data bank on failures, damages, and emergency situations at hydroelectric plants throughout the world, 76% of all emergency situations are associated with the development of natural and techno-natural processes (Table 1).
