兰州轨道交通1号线对白衣寺影响数值分析

兰州轨道交通1号线因考虑到客流和线网的因素不得不侧穿省级保护文物白衣寺,因此须确保在盾构施工和运营期间白衣寺的安全。分析得出:采用隔离桩保护措施进行加固对控制施工沉降有显著效果;采用钢弹簧浮置板道床时列车运行振动对地表影响有明显改善。

Numerical analysis on inlfuence of line 1 of lanzhou rail trafifc on white temple

Take into account the factors of passenger flow and line network, Line1 of Lanzhou rail traffic have to pass through the side of provincial heritage conservation units White Temple, Therefore in the shield consmlction and operation period, We must ensure the safety of white temple.The result indicates that：the White Temple will be affected by the shield construction, isolation piles can significantly reduce the settlement amount by the shield construction;floating slab tracks can effectively reduce the ground vibration.
