摘要
以北京地铁十号线工体北路站为依托工程,在定性分析洞桩法顺筑及逆筑方案特点的基础上,基于模糊优化理论建立了浅埋暗挖地铁站施工方案的多目标模糊优化模型,对车站施工方案的选择问题进行了探讨。结果表明:工体北路站采用CRD工法、洞桩法逆筑方案及顺筑方案均有一定的可行性,为了确保地表沉降得到控制,最终确定洞桩法逆筑方案为最优方案,研究结果可供类似工程参考。
Taking the Gongti North Road station of Beijing metro line 10 as an example and based on the characteristic analysis of sequential and inverse construction schemes with PBA method, this paper established a multi-objects fuzzy optimization model of shallow buried metro station construction schemes by using fuzzy optimization theory and discussed the selection of the station construction schemes. The results showed that CRD tunneling method, sequential and reverse construction methods with PBA are all feasible for Gongti North Road station construction and the reverse construction method with PBA was taken as the best solution for the sake of ground settlement reduction, which could be a reference to similar projects.
