摘　　要：在深厚软土地基上进行道路工程,软土的沉降固结规律是设计和施工的分析重点。该文结合上海宝钢滩涂圈围区域道路工程实例,利用岩土工程有限元软件PLAXIS,模拟路基的分层填筑施工过程,分析地基变形和应力的变化,从而认识该区域软土沉降固结的发展规律,为设计和施工控制提供依据。Consolidation and settlement characteristics of soft soil are major concerns during the design and construction of road projects in deep soft soil areas. The deformation and stress changes of soft foundation are analyzed under preloading in a shoal hydraulic fill area of Baoshan Iron ＆ Steel Co., Ltd. in Shanghai, and the geotechnical finite dement soft PLAXIS is used to simulate the layered buried progress of soft soil founda- tion, the change of ground deformation and stress are analyzed, so the law of consolidation and settlement devel- opment is obtained, and it provides the basis for the design and construction control.
