| 中文摘要:两河口水电站公路边坡开挖后揭露的局部地质情况为强风化、强卸荷反倾薄层～中厚层砂板岩，节理裂隙发育，围岩破碎，裂隙张开，松动卸荷较强烈，设计对该边坡增加框格梁及无粘结钢绞线压力分散型预应力锚索进行加强支护。主要介绍在地质情况差的区域进行预应力锚索灌浆施工时的超灌浆控制技术。 |

| Abstract:The local geological conditions are strong weathered, strong unloading anti-dip thin layer-middle-thick layer sand slate with joints and fractures developing, broken surrounding rocks, open fissures and serious loose unloading in road slope excavation at Lianghekou hydropower station. The frame beams and non-cohesive steel strand dispersion-type pre-stressed anchorage cable were designed to reinforce the side slope. The paper describes the super grouting control technique for pre-stressed anchor grouting in poor geological conditions. |
