摘　　要：立足于上海市松江有轨电车T1线工程项目实例,通过对土层物理力学参数差异性分析,应用有限元方法研究深厚软土有轨电车路基不均匀沉降问题。在控制沉降的基础上,对有轨电车采用的桩板结构、换填、复合地基等3种轨下基础设计方案进行了分析与比选。结果表明,桩板结构方案下有轨电车路基总沉降为10.1~13.3 mm,其沉降控制效果较好。Based on the practical case of Songjiang Tram Line T1 in Shanghai,through difference analysis of physical and mechanical parameters of soil layer,the problem of tram subgrade uneven settlement in deep soft soil is studied by using finite element method.On account of settlement control,three sub-rail foundation design schemes are analyzed and comparatively selected,including pile-slab structure,filling replacement and composite foundation.Results show that the total set-tlement of tram subgrade in pile-slab structure scheme is 10.1~13.3 mm,the settlement control effect is relatively good.
