摘要
天生桥二级水电站为一大型引水式水电工程,随着厂房基坑开挖的进展,厂房后边坡岩(土)体发生明显滑移,为掌握其滑移动态,在边坡上埋设了两个测斜孔,应用CX-01型测斜仪对厂房后边坡进行了监测.监测结果表明,滑坡体上部由于削坡减载而趋于稳定;下部仍在滑移,最大滑移速度为0.5mm/d.文中还叙述了该水电站厂房边坡的地质条件、监测仪器及其布置埋设,可供借鉴.
The Tianshengqiao No.2 hydroelectric power project is a large hydroelectric engineering. During the period of excavation, the slip of slope was happened clearly. In order to know the sliping, the CX-01 inclinometer was used to monitor the slope. In this paper, provided the results of monitoring. The geological conditions in the slope of power house, monitoring instruments and its management were also introduced.
