铁路线侧平式站房地基处理和站坪土方探讨

Discussion on Foundation Treatment and Station Earthwork of Railway Station Building with Same Level of Platform

当铁路线侧平式站房位于站坪填方上时,站房的地基处理常常需要付出很大代价。通过分析喀和铁路(喀什一和田)站房建设,从3种典型站房的工程概况及地质条件,以及站房的基础形式和地基处理方案,分析计算了站房基础施工的主要工程量和造价,通过技术经济比较表明,位于高填方站坪上的线侧平式站房应先进行站房基础施工,后进行站坪填土作业,以减少工程造价。

When railway station building with same level of platform is located above station filling, the foundation treatment of station building generally needs great paid. Through analyzing the station building construction of Kashi-Hetian railway, this paper analyzes and calculates the main engineering volume and cost of station building infrastructure from engineering situation and geological condition of 3 typical station buildings as well as basic form and foundation treatment program of station building. Through technical and economic comparison, the result shows that the station building with same level of platform located on high filling site should implement station building basic construction firstly, and then implement station filling operation, so as to reduce engineering cost.
