现代有轨电车无砟轨道路基与传统的有砟轨道路基、客运专线无砟轨道路基相比，有一定的差别。结合工程设计经验，从路基面、基床厚度及填料要求、沉降要求、排水方面对现代有轨电车路基设计进行分析与论述,对无砟轨道路基结构进行计算分析，量化基床厚度、基床表层厚度、基床底层厚等技术指标，可为其他新建有轨电车工程设计提供参考。

Modern tram ballastless subgrade is different from traditional ballastless tracks and those ballastless tracks of dedicated passenger railways. On the basis of the engineering design experiences, the design of subgrade of modern trams was analyzed and discussed with comprehensive consideration of subgrade surface, the thickness of the subgrade bed, filler requirements, the settlement requires and drainage.
