摘　　要：介绍了旺盛江水库第二溢洪道滑坡体初设加固方案的设计分析与比选计算的内容。通过计算分析论证了边坡稳定性存在的问题,提出了削方减载方案、抗滑桩方案和格构锚固方案3种边坡加固的初设方案,并结合工程实际条件对各方案进行了设计和比选分析。结果表明,推荐采用的抗滑桩方案在工程安全、施工技术和投资成本方面有很大优势。An introduction was made on the design,analysis,comparison and calculation of initial reinforcement schemes for the landslide of the second spillway of Wangshengjiang Reservoir.The existence of slope stability problem is proved by calculation and analysis.Three initial slope reinforcement schemes are proposed including the cutting square and reducing load scheme,anti-slide pile scheme and lattice anchorage scheme.Combined with the actual engineering conditions,the proposed schemes were designed and compared.The results of comparison demonstrate the recommended anti-slide pile scheme has great advantages in engineering safety,construction technology and investment cost.
