为加强向家坝水电站蓄水期间的安全监测，对枢纽建筑物实施了变形（水平及垂直位移、接缝开合度和基岩变形）、渗流渗压以及应力应变监测，并开展了泄洪消能建筑物水力学专项监测工作，获取了大量监测数据。监测结果分析表明，大坝蓄水后，大坝主体、右岸引水发电系统、边坡等部位的变形、应力应变以及渗流渗压值均趋于稳定，变化规律基本合理。枢纽建筑物工作性态总体正常。%To strengthen the safety monitoring of Xiangjiaba Hydropower Station in the impoundment period , the deformation of the structures ( horizontal and longitudinal displacement , openings of joint and bedrock deformation ) , seepage and seepage pres-sure, and stress and strain were monitored .The special hydraulic monitoring was implemented to the flood release and energy dis -sipation structures.The results show that after the impoundment , the deformation, stress and strain and seepage pressure of the dam body, water diversion and power generation system at right bank and the side slope tends to be stable , and the variation law is reasonable .The operation of the hydro -complex structures is in a normal state .
