云南万家口子水电站碾压混凝土拱坝安全监测系统设计

Design of Safety Monitoring System for RCC Arch Dam of Wanjiakouzi Hydropower Station in Yunnan Province

万家口子水电站工程最大坝高167.5 m,工程地质情况复杂。为了实现对建筑物的安全监控,根据规范要求并结合工程地质的特点,笔者详细介绍坝体、坝基、坝肩的变形监测,坝体温度计应力应变监测,渗流监测,边坡监测及科研项目监测等设计内容。经过对现场的监测数据分析,结果基本反映了大坝的运行状况。

The maximum dam height of Wanjiakouzi Hydropower Station is 167.5 m,and the engineering geology is complex.In order to realize the safety monitoring of buildings,according to the requirements of the code and the characteristics of engineering geology,this paper introduces in detail the deformation monitoring of dam body,dam foundation and dam shoulder,stress-strain monitoring of dam body thermometer,seepage monitoring,slope monitoring and scientific research project monitoring.Through the analysis of the monitoring data,the results basically reflect the operation of the dam.
