摘要
董餐水电站坝址处于砂泥岩地区,边坡岩体风化速度快,其中钢筋混凝土面板堆石坝右岸趾板以上边坡为顺向坡,存在失稳的可能性。本文通过分析右岸趾板以上顺向坡的特性,采用锚索深层加固和锚筋柬浅表层支护,加强地表和地下排水措施,成功解决了该砂泥岩边坡的稳定问题,可供其他类似工程参考借鉴。
The dam site of Dongqing hydropower project is located in the sandy mud area, where the slope rock weathers hardly and the slope above the plinth on the right bank of the reinforced CFRD is a consequent slope and therefore there is a possibility of instability. After analyzing the property of the consequent slope above the plinth on the right bank, cable anchorages and anchor bars are respectively used in the deep layer and in the surface layer to strengthen the surface and underground drainage measures, so the problems of the sandy mud slope stability are successfully solved. It offers reference for the other similar projects.
