旭龙水电站导流洞施工期安全监测与围岩稳定分析

Safety Monitoring and Stability Analysis of Surrounding Rock during the Construction Period of the Xulong Hydropower Station Diversion Tunnels Project

介绍了旭龙水电站导流洞工程地质概况、安全监测设计和监测施工,通过对围岩变形、渗压渗流、应力应变和温度等监测数据的采集分析,对导流洞洞身的稳定性、安全度做出评价,系统掌握导流洞施工开挖过程围岩的变形与应力应变规律。施工期安全监测在施工过程中起到了反馈设计与指导施工的良好作用。

The paper presents the engineering geological conditions,safety monitoring design,and monitoring construction of the diversion tunnel at Xulong Hydropower Station.Through the collection and analysis of data on deformation,seepage pressure,stress and strain,and temperature of surrounding rock,the stability and safety level of the tunnel structure are evaluated.The deformation and stress-strain patterns of surrounding rock during construction and excavation of the diversion tunnel are systematically understood.Safety monitoring during construction plays a crucial role in providing feedback for design adjustments and guidance during construction.
