涉铁道路设计要点初探——以株洲市中车大道设计为例

Brief Discussion on Design Essentials of Railway Related Road

近年来道路涉铁项目日益增多。一般常规涉铁道路的设计主要考虑道路与铁路交叉节点的设计。结合湖南省株洲市中车大道项目的设计,提出在涉铁道路总体方案设计时,除道路与铁路节点的设计方案,还需考虑道路周边涉铁大型厂区对设计方案的影响。介绍了周边大型涉铁厂区抗震防尘需求,对道路线位、路基设计方案的影响。结合涉铁厂区提供的铁路机车整车运输资料,介绍了满足涉铁运输需求前提下的道路净空、路面结构设计。介绍了道路与铁路节点(上跨试车线、下穿城际铁路)的设计要求和方案,在下穿城际铁路方案中提出了利用铁路变截面梁高,满足中车大道对铁路整车运输净空要求的特殊设计,节约了投资。介绍了道路与铁路节点设计中铁路安全防护设计要求。

In recent years,the number of railway related road projects is increasing.The design of the general conventional railway related road is mainly to consider the design of the road and railway intersecting node.Taking the design of Zhongche Avenue in Zhuzhou City of Hunan Province as an example,it is proposed that the influence of railway related large-sized factories surrounding the roads on the design schemes should be considered besides the design scheme of road and railway node during the design of the overall scheme for railway related road.Combined with the truckload transport information of railway locomotive provided by the railway related factory,the design of road clearance and pavement structure under the premise of meeting the demand of railway transportation is introduced.The design requirements and schemes of road and railway nodes(overpass testing line,underpass interurban railway)are introduced.The utilization of railway variable cross-section beam height is proposed in the underpass interurban railway scheme to meet the special design of the clearance requirement of Zhongche Avenue for railway truckload transport and to save the investment.The design requirements of railway safety protection in the node design of road and railway are introduced.
