INTEGRATION OF SEISMIC DATA INTO DAM SAFETY MANAGEMENT SYSTEMS: STATE CRITERIA AND MONITORING

Abstract

The safety of hydraulic structures (HS), particularly dams, in seismically active regions, represents a critical task in engineering practice. This article considers an integrated approach to incorporating seismic data at all stages of a dam’s lifecycle—from site selection to operation. Special attention is given to the system of safety criteria indicators (K1 and K2), which define the transition of a structure from normal operation to potentially hazardous and pre-failure conditions. The role of automated monitoring systems, including seism metric instrumentation, in operational decision-making is analyzed. Based on the analysis of regulatory requirements and historical precedents (for example, the Sardoba reservoir accident), the necessity of continuous monitoring of foundation deformation and filtration parameters under seismic loading is substantiated.
