摘要
如何较好满足车辆段与综合基地的使用功能要求,是站场布置设计需着重考虑的因素;因地制宜,结合设施需求充分利用空间是车辆段设计的关键。车辆段与综合基地占地面积大,场坪高程及地基处理方案对工程造价影响较大,依据百年一遇水位及基本地勘资料确定填方高程和地基处理方案很难达到最优方案设计,应通过相应专题研究及试验最终确定车辆段场坪高程和地基处理方案。结合郑州市轨道交通1号线一期工程郑东车辆段站场设计布置原则及方案、场坪高程和路基处理方案的确定,对相关问题进行阐述,为车辆段站场布置等提供参考。
For the station yard design of Zhengzhou east rolling stock depot in first stage projects of Zhengzhou Urban Rail Transit line 1, this paper illustrated how to determine the layout principle, layout scheme, site elevation, and the subsoil treatment scheme; and then expounded relevant issues, providing reference for station yard layout design of similar rolling stock depot. This paper pointed out: (a) How to better satisfy functional requirements of a rolling stock depot and comprehensive base is an issue needing to be emphatically considered in design of station yard layout. Moreover, the key to rolling stock depot design is: taking effective measures according to local condition, and making full use of space in combination with facility demand. (b) When determining the earth filling elevation and subsoil treatment scheme, it is difficult to achieve an optimal design only based on once-in-a-hundred-years highest flood level and basic geological exploration data, because the covering areas of rolling stock depot and comprehensive base are very large, and because the depot's site elevation and subsoil treatment scheme have great effect on project cost. So, relevant monographic study and experiment should be carried out so as to finally determine site elevation and subsoil treatment scheme of a rolling stock depot.
