某混凝土重力坝水平位移综合分析

Comprehensive Analysis of Horizontal Displacement of a Concrete Gravity Dam

介绍某混凝土重力坝水平位移采用引张线结合垂线的监测方法,根据大坝结构、水位、温度进行大坝水平位移综合分析。某混凝土重力坝水平位移与坝体结构、坝上下游水位、坝体温度有较强的相关性,主要表现为坝上水位升高时坝体向下游位移,坝上水位降低时坝体向上游位移,坝体温度降低时大坝收缩,坝体温度升高时大坝膨胀。

The monitoring method of horizontal displacement of a concrete gravity dam is introduced.According to the dam structure,water level and temperature,the horizontal displacement of the dam is comprehensively analyzed.The horizontal displacement of a concrete gravity dam has a strong correlation with the dam structure,upstream and downstream water level and dam body temperature.The main performance is that the dam moves downstream when the upstream water level rises,the dam moves upstream when the upstream water level decreases,the dam shrinks when the dam temperature decreases,and the dam expands when the dam temperature rises.
