地铁轨排井结构三维有限元优化设计

Three-dimensional Finite Element Optimal Design of Subway Track and Discharge Structure

结合广州地铁六号线长湴站~植物园站区间工程,分别采用二维计算和三维有限元分析对轨排井结构进行计算分析,对轨排井结构内力进行对比,三维有限元分析的内力结果减少较多,据此对轨排井结构设计提出了建议。

Based on the two-dimensional calculation and three-dimensional finite element analysis,the structure and structure of the track and well row are analyzed and analyzed.The internal force of the track and drainage structure is compared and the threedimensional finite element analysis is carried out.Of the internal force results to reduce more,according to the structure of the rails and drainage wells.
