摘要

Use of the method of seismic tomography permits on-going and highly detailed exposure of weaken sections of structures and their beds. The problem of ensuring the stability of water-development works (WDW) remains one of the most critical in-service problems of these structures. Strong crystalline rocks, which ensure reliable WDW performance throughout their significantly lengthy service lives, are the beds of earth dams and dikes built on the Kola Peninsula. As a rule, damage sustained by water-development works formed from fill soils may be caused by an unfavorable filtration regime in the body of the structure, as a result of which suffosion processes, and, correspondingly, suffosion deformations of the structure develop [1,2]. At the same time, the natural jointing of the beds, and zones of tectonic disturbances and fractures that intersect the WDW may also substantially degrade the in-service operating regime of the dams. Reliable, ongoing information on the internal structure of the earth-dam/bed system will appreciably diminish the risk of appearance of unscheduled emergency situations.
