摘要
结合杭州地铁某地下两层车站,进行增设轨排井的方案比选,针对左右线两侧分别设置轨排井方案,分别建立二维模型和三维模型进行有限元数值计算。根据计算结果研究车站设置轨排井结构的内力分布及变形规律,重点对侧墙进行对比分析,核实两种模型计算结果的一致性规律和差异原因,通过现场施工实施效果验证方案的可靠性和计算结果的可行性。
Combining with a Two-story underground station of Hangzhou metro, the scheme of adding track panel shafts are Compared and selected. Based on the scheme of setting track wells on both sides of the left and right lines, two-dimensional and three-dimensional model are established respectively for finite element numerical calculation. Besides,accordingto the calculation results, the internal force distribution and deformation law of the track panel shaft structure is studied. Especially,this paper focus on the comparative analysis of the side walls,and the consistency law and difference reason of the two models are verified. Finally the reliability of the scheme and the feasibility of the calculation results are verified through the construction implementation effect.
