摘　　要：由于旺盛江水库第二溢洪道存在混凝土老化、钢筋外露与地基碎裂等问题,为了保证滑坡体处理的安全可靠,初步设计采用了"抗滑桩+锚索"的方案进行加固;随后结合实际工程条件,对原加固方案进行了优化调整,并提出了另一种优化加固方案,即"箱涵+锚索"方案,最后从多方面对两优化方案进行了较为详细的比选分析。结果表明,"抗滑桩+锚索"的优化加固方案具有无需变更程序且能确保施工工期的优势,且加固后的滑坡体的稳定性明显提高。The second spillway of Wangshengjiang Reservoir has problems such as aging of concrete,exposed reinforcement and ground breakage.In order to ensure the safety and reliability of landslide treatment,the preliminary design adopts the scheme of"anti-slide pile+anchor cable"for reinforcement.Then,combining with actual engineering conditions,the original reinforcement scheme is optimized and adjusted,and another optimized reinforcement scheme,namely"box culvert+anchor cable"scheme,is put forward.Finally,the comparison and analysis of the two optimization schemes are carried out in detail from many aspects.The results show that the optimized reinforcement scheme of anti-slide pile+anchor cable has the advantages of no need to change the procedure and can ensure the construction period,and the stability of the reinforced landslide mass is significantly improved.
