Monitoring Index of Horizontal Displacement of Concrete Dam Based on Strength Reserve Method

Chaoyang Fang

Abstract

In order to study the dam monitoring index,taking overflow section #18 of Feilaixia concrete dam for an example,the strength reserve method is applied to calculate the horizontal displacement component of monitoring points under the special conditions of initial yield,critical buckling and unstable failure.And then hybrid model of the dam horizontal displacement is established by combining the statistical model of temperature component and time-dependent component of the dam top horizontal displacement.Finally,the safety monitoring index of the displacement for overflow section #18 of Feilaixia project are obtained.
