摘要
龙滩水电站右岸岸坡地质条件异常复杂,采用锚固洞塞的加固方案对边坡稳定进行治理。针对此工程设计要求高、技术难度大等特点,对爆破控制、洞室开挖出渣、锚杆注浆等施工方法进行了改进,提高了施工工效,加快了施工进度,最终提高了经济效益。
Due to the very complex geological condition on the right bank of Long-tan hydropower station, the side slope has been treated with anchored-tunnel in order to get its stability. Aiming at high design requirement and great technical difficulties, construction methods such as blasting control, excavating and mucking in the tunnel and grout injection in the holes with anchor have been improved on so as to advance construction efficiency, quicken construction schedule and increase economical benefits finally.
