摘　　要：基于巢湖湖区口门导堤工程设计,对软土地基上抛填导堤进行了分析。为研究抛填导堤的稳定性,采用理正岩土-软土堤坝模块和有限元软件MIDAS-GTS-NX建立了模型,导入土体e-p值,对抛填导堤施工期的稳定和沉降进行了计算。依据计算结果优化的导堤断面,提出合理的施工顺序和技术参数。Based on the engineering design of the guide dike at the entrance of Chaohu Lake area,the dumping and filling of the guide dike on the soft soil foundation is analyzed.In order to study the stability of the dumping guide dike,the model is established by using Lizheng geotechnical soft soil dike module and finite element software MIDAS-GTS-NX,import the e-p value of soil,and the stability and settlement of the dumping guide dike during the construction period are calculated.According to the optimized guide dike section according to the calculation results,the reasonable construction sequence and technical parameters are put forward.
