现代有轨电车路基优化设计分析

通过国内现代有轨电车建设、运营、设计、科研等单位的调研和分析,采取比较和设计归纳总结等方法,就基床坡率设计、路面高低覆盖绿化率、安全防护范围、排水设计以及与道路搭接5个方面进行探讨及优化,推荐路基标准横断面图;分析铁路A、B组填料直接应用到路基工程中的弊端,提出基床底层A、B组填料宜选择小于6cm的碎石类、砂类土的建议;剖析既有路桥过渡段设计现状且考虑其不均匀沉降及刚度过渡的问题并提出优化方案。

Optimal Design Analysis of Subgrade of Modern trams

Through research and analysis conducted by the participants in the construction,operation,design and scientific research of domestic modern trams and the comparison,summary and design,five aspects such as the bedding slope rate design,pavement,safety protection of high and low coverage scope,drainage design and road lap are discussed and optimized,and roadbed standardized crosssections are recommend. Analysis of railway A, B group of filler applied directly indicates their disadvantages in subgrade engineering and the bed bottom packing with A,B group of gravel,sand soil less than 6 cm should be selected. With a view to the present condition in the design of the existing bridge transition section design, the uneven settlement and the stiffness transition problems, the optimization scheme is put forward
