善泥坡水电站调压井监测资料整编及反馈分析

The Monitoring Data and Feedback Analysis of the Surge Shaft in the Shannipo Hydropower Station

通过监测资料分析,调压井竖井段变形和锚杆受力均不大,竖井段混凝土浇筑完成以及调压井灌浆时期,围岩变形和受力有所波动,但是岩层之间没有错动和脱离趋势,围岩稳定;调压井结构监测测值变化规律相对较为稳定,波动小,结构安全,调压井在施工及运行期的观测资料分析表明:调压井结构是在安全、正常的状况下运行的。同时各种观测资料提供了调压井当前状况的科学数据,对设计、施工方案和技术措施进行校核验证,并为今后的设计积累一定的经验。

Through the analysis of monitoring data,the deformation and stress of the anchor rod of the shaft section of the surge shaft are not large.After the completion of the concrete pouring of the shaft section and during the grouting period of the surge shaft,the deformation and stress of the surrounding rock fluctuate,but there is no dislocation and separation trend between the rock layers,and the surrounding rock is stable.The observation data analysis of the surge shaft in the construction and operation period shows that the surge shaft structure operates in a safe and normal condition.At the same time,various observation provides scientific data of the current situation of the surge shaft.The design,construction scheme and technical measures are checked and verified,and some experience is accumulated for the future design.
