摘　　要：通过泉州海湾大道工程案例,分析项目地质情况、软基路段分布情况、土体参数,从常用的浅层、中层、深层软基处理方法中初选软基处理方案。通过地基处理计算、软基段边坡稳定分析及沉降分析等方法充分比选各方案的技术可行性。在技术可行的基础上,通过施工可行性及工程投资等方面对各方案进行综合比选,选出适应本项目不同深度的最优方案。同时,对存在软基的特殊断面位置进行特殊处理。在控制总沉降的同时,过渡特殊位置的差异沉降,使设计方案能够达到良好的处治效果,满足设计使用要求。In this study,we analyzed the geological situation of the project,the distribution of soft foundation section and the soil parameters through the engineering case of Quanzhou Bay Avenue,and selected the soft foundation treatment scheme from the commonly used shallow,middle and deep soft foundation treatment methods.The technical feasibility of each scheme is fully compared by means of foundation treatment calculation,slope stability analysis and settlement analysis.On the basis of technical feasibility,through the comprehensive comparison of the aspects of construction feasibility and project investment,the optimal scheme adapted to the different depths of the project.At the same time,a special treatment is given for the special section location of the soft foundation.While controlling the total settlement,the differential settlement of the transition special position enables the design scheme to achieve good treatment effect and meet the design requirements.
