摘　　要：周宁水电站地下厂房及引水系统的监测项目包括围岩变形监测、锚杆应力计监测、渗透压力监测、测缝计监测。采用的监测仪器分别为:RW-40型多点位移计、KL型锚杆应力计、PWS型渗压计、CF-12型测缝计、DI-10型三向应变计。监测仪器随着地下厂房分层开挖而分层埋设。施工期采用手工巡测,人工测读记录,然后将观测数据输入微机进行分析、整理。根据监测结果可以验证厂房边墙加固措施的效果,指导行车运行及引水系统充排水过程等,并可适时掌握高压管道和地下厂房安全运行性态。The monitoring project of Zhouning Hydropower station underground plant and water intake system including monitoring of the surrounding rock deformation, bolt stress, osmotic pressure and joint. The meters are： rod extensometer, bolt stress meter, osmotic press, joint meter, triaxial stress meter.All the meters are stratified embedded along the Stratified Excavation of the underground plant. During construction period, all the data is checked manually and input to computer to be analysed. The analysis results can be used to check the Reinforcement Measures for the plant wall, also can be a instruction for the crane operation and water intake： system operation. So the safe operation of the high-pressure pipes and the undergrund plant is under control all： the time.
