现代有轨电车路基设计的几点思考和建议

为保证有轨电车的安全性、舒适性、经济性,提出现代有轨电车一般路基工后沉降不应大于50 mm的标准;路基基床厚度采用1.2 m,桩顶垫层作为下挖式路堤基床底层的设计理念;认为路基基床底层填料的选择应与两侧道路相一致,同时对常规路基排水提出方案优化。表明路基工后沉降、路基本体填料的选择和厚度的确定、路基排水措施的有效性都是影响路基正常使用的关键因素。

Modern tram roadbed design some thoughts and Suggestions

In this paper, the modern tram general subgrade should be not greater than 50 mm post-construction settlement standards; Subgrade bed thickness using 1.2 m, under the cap cushion as digging type embankment foundation bed at the bottom of the design concept; Subgrade bed underlying the choice of packing should be consistent with on both sides of the road, at the same time of normal roadbed drainage scheme optimization is put forward.
