摘要

介绍了一种水电站大坝技术状态辅助监测的方法。它是基于对大坝动力特性变化的分析,这些变化是由记录结构微震振动的自动监测和地震登记系统获得的。介绍了该系统的组成及克拉斯诺亚尔斯克水电站大坝的地震监测结果。为了研究大坝在正常荷载和极限荷载作用下的受力特性,提出了用有限元方法建立大坝模型的方法。

Monitoring the technical condition of dams of hydroelectric power plants with an automated monitoring and earthquake registration system
An approach is described that has been developed for auxiliary monitoring of technical condition of hydropower plant dams. It is based on analysis of changes in dynamic characteristics of dams obtained by an automated monitoring and earthquake registration system that records microseismic vibrations of structures. The configuration of the system as well as the results of seismometric monitoring of the dam of Krasnoyarsk hydroelectric power plant are described. To study behavior of the dam under normal and extreme loads it was proposed to develop a model of the dam with the use of the finite element method.
