NUMERICAL STUDY OF COMPACTION OF THE EARTH DAM BODY IN THE POST-CONSTRUCTION PERIOD

Abstract

Ensuring the operational reliability of hydraulic structures is an important task at the stage of the life cycle of the structure. The main reasons of destructions of hydraulic structures in the course of research were identifi ed as errors in the design of such structures and their construction, or the absence of operating organizations and, as a result, the lack of proper maintenance for such structures. Such errors inevitably lead to the creation of defects in the body of hydraulic structures with the subsequent development of deformations and destruction of hydraulic structures because of a violation of the fi ltration strength. In this regard, standard methods for assessing operational reliability appear to be cumbersome and ineffi cient in the conditions of a short time allotted for assessing the degree of damage to the structure, obtaining reliable results on the current level of operational condition of hydraulic facilities, taking into account the physical and mechanical properties of the materials, the degree of damage and the characteristics of the operation.
