浅埋大跨平拱隧道地表沉降原因分析

Analysis on Ground Settlement of Shallow Buried Wide Span Gently Arch Tunnel

针对人行隧道在施工过程中实测地表沉降超出预计沉降量 ,利用三维有限元对该隧道的施工过程进行计算模拟 ,通过计算值与实测值的对比 ,并综合考虑其他因素的影响 ,对该隧道的地表沉降原因进行了综合分析 。

The actual ground settlement of a sidewalk tunnel is much more than the expectation By 3 dimention finite element simulation of construction, contrasting the calculating result with the actuality and considing other factors,the ground settlement of the tunnel is comprehensivly analysed and some suggestions on simular projects are given
