摘　　要：为了评价某病险防洪堤整治工程,基于Geo-Studio软件,利用该软件中的SEEP/W软件与Slope/W软件,对该堤防在正常蓄水位、设计洪水位以及设计洪水位骤降工况下的渗流与稳定进行了计算与分析,同时利用Slope/W软件对在挡土墙进行抗滑稳定和抗倾覆稳定分析。计算结果表明,该堤防满足渗流与稳定设计要求,渗流并不是控制该堤防稳定的主要因素,正常蓄水位与设计洪水位下其稳定性主要由背水侧挡土墙的稳定性决定,而设计洪水位骤降工况下的稳定性则由临水侧挡土墙决定。Geo-Studio具有较强大的渗流和稳定分析功能,其计算成果可为较复杂的类似工程问题提供参考。To evaluate the renovation project of dilapidated levee,based on the SEEP/W and Slope/W modules in Geo-Studio software,this paper calculated and analysed the seepage and stability of the levee under normal storage level,design flood level and design flood level dips.The stability against sliding and overturning of retaining wall was analysed by the Slope/W module.The results show that,the seepage and stability of the levee could meet the design requirement,seepage is not the main factor to affect the stability of levee.The stability of levee depends on back water retaining wall under normal storage level and design flood level,and depends on waterfront retaining wall under design flood level dips.The Geo-Studio software has powerful features for the analysis of seepage and stability,and the calculation results could provide reference for similar engineering.
