应用自动测值反演坝体弹模和拟定位移监控指标

大坝监测自动化是大坝安全监测的发展方向,为更好地为大坝安全监测服务,利用自动监测系统测值对陈村大坝的综合弹性模量进行了反演和变形监控指标的拟定。介绍了反演分析的基本原理和方法,以陈村水电站18#坝块作为典型坝段进行了反演分析,并根据实测资料,拟定了陈村典型坝段坝顶水平位移监控指标。结果说明自动监测系统的测值是可信的,可用于评估大坝安全。

Inversion of Dam Body Elastic Modulus and Determination of Displacement Monitoring Index from Automatic Measured Data

Automatic monitoring for dam is development direction of monitoring for dam safety. In order to provide better services to monitoring for dam safety, inversion of comprehensive elastic modulus and determination of displacement monitoring index of Chen village dam are achieved by using data measured by the automatic monitoring system. This article introduces basic principles and methods for inversion analysis. NO.18 dam section of the dam is applied as a typical example for the inversion analysis. Horizontal displacement monitoring index is determined based on measured materials. The results have verified the system measured data are credible and can be used in evaluation for dam safety.
