摘　　要：介绍了桑坪水电站调压井高边坡在破碎岩体中采用迈式自钻式中空注浆锚杆,对破碎岩体及浅层塌方体的围岩固结锚固技术起到了很好的效果,对加快施工进度、降低施工难度、提高经济效益等方面都起到了较好的作用,为相似地质条件下的水电工程施工提供了参考。For construction of surge tank of Sangping hydropower station, the stepping and self-drilling hollow grout injection anchor rods are used in fractured rock at high slope and shallow landslide, resulting in good consolidation and anchorage in the surrounding rock. Furthermore, construction progress is speeded up, construction is made less difficult and economic benefit is improved. This technique provides some references for the construction under similar geological conditions.
