摘　　要：安昌河水电站调压井边坡位于陡坡中部倾倒变形体之上,工程投产后调压井边坡多次出现变形、滑塌,但一直未得到有效治理,致使井筒被剪裂,面临水电站停运、或调压井改建状况。通过边坡地质勘察、稳定性计算、分析研究后,根据工程现状及环境条件,制定并实施了调压井边坡增稳治理措施、进行边坡变形观测,达到边坡有效治理、安全稳定、水电站正常运行之目的,可作为类似工程边坡治理参考借鉴。The slope of surge shaft of Anchanghe Hydropower Station is located on the toppling deformation body in the middle of the steep slope.After putting into operation,the slope of surge shaft has been deformed and collapsed many times,but it has not been effectively treated,resulting in the shaft being fractured and facing the situation of shutdown of the hydropower station or the reconstruction of surge shaft.Based on the geological investigation,stability calculation and analysis of the slope,and according to the engineering status and environmental conditions,this paper formulates and implements the measures for stabilizing the slope of surge shaft,and observes the deformation of the slope,so as to achieve the goal of effective slope control,safety and stability,and normal operation of the power station.It can be used as a reference for slope control of similar projects.
