摘要
大跨车站开挖过程中,受浅埋近距离多洞室等复杂情况的影响,隧道围岩呈现出非线性沉降,因此这种地铁车站开挖必须实施信息化施工。通过地表监测及时掌握围岩力学状态,及时采取对策,实施动态施工,以确保隧道暗挖施工安全。
Being influenced hy the complicated conditions from the excavating of shallow buried multi-eaves with ultra-short distance between each other, the non-linear settlement of surrounding rock is occurred in the course of excavating of the large span subway station. It is essential to adopt informatization construction method while excavating this kind of subway station. To ensure the safety of the station, dynamic construction is needed, we should take response action in time, according to the mechanics condition of surrounding rock.
