基于监测数据的顶山输水隧洞工程运行性态分析

Analysis on Operation Behavior of Dingshan Water Transfer Tunnel Project based on Monitoring Data

文章以顶山长距离输水隧洞为研究对象,介绍了地质条件和安全监测布置情况,结合运行20余年来的监测数据,绘制了过程线、分布图,统计了典型测点的特征值,对工程运行性态进行了分析评价,结果表明围岩变形和受力仍未收敛。文章的分析思路和成果可为新建工程监测布置和已建工程的资料分析提供借鉴。

Dingshan long distance water transfer tunnel is regarded as the research object in the paper.The geological conditions and safety monitoring arrangement are introduced.The monitoring data of operation for more than 20 years is combined to draw the process line and distribution map.The characteristic values of typical measuring points are counted.The operation behavior of the project is analyzed and evaluated.The results show that the deformation and stress of surrounding rock is not converged.The analysis ideas and results of the paper can be used as reference for monitoring layout of new projects and data analysis in existing projects.
