西藏DG水电站大坝安全监测系统设计

Design of the Dam Safety Monitoring System for Xizang DG Hydropower Station

基于相关规程规范和已建工程经验,结合西藏DG水电站坝址区水文地质条件、枢纽工程的布置及各建筑物结构形式,各项安全监测设施的特点,研究建立了大坝自动化安全监测系统。电站下闸蓄水至今,大坝安全监测系统运行正常,变形、位移、渗流等实测资料、现场巡查及相关复核计算成果表明,大坝工作性态正常,满足设计和相应规程规范等要求,自动化安全监测系统可供类似工程设计参考。

Following the relevant regulations and specifications and the experience of existing projects,and also considering the hydrogeological conditions of the dam site area,the layout of the project,the forms of various structures,and the characteristics of various safety monitoring facilities,an automatic dam safety monitoring system is established in Xizang DG Hydropower Station.Since the impoundment of the station,the dam safety monitoring system has been operating normally.The measured data on dam deformation,displacement and seepage,on-site inspection and relevant calculation results show that the working behavior of the dam is normal and fulfills the requirements of the design and corresponding regulations.The design of the dam safety monitoring system can be useful reference for similar projects.
