| 摘 要： | 以临近莞惠线新城车站的某市控制中心深基坑工程为背景,基于理正软件验算基坑支护结构,并将有限元软件Midas-sws及Plaxis结合,建立了既有渗流场、位移场的情况下深基坑按实际开挖工况的三维数值模型,以紧邻车站变形量和基坑结构应力最小为优化目标,对开挖工法进行优化,并分析了基坑开挖对新城站地铁的影响评估,可以为优化设计和安全施工提供有益的参考。

| Abstract: | Based on deep excavation of OCC closed to Xincheng station of Guan-Hui line, using Li-zheng to check pit supporting structure, and combining with the finite element software Midas-sws and Plaxis, under the seepage field and displacement field, the deep foundation is simulated and analyzed according to the actual excavation conditions. To structure stress and foundation pit deformation station near the minimum as the optimization goal, optimize the excavation method, and the impact assessment is building on the foundation pit excavation and metro station metro, can provide a beneficial reference for optimization design and safety construction. |
