摘要
针对广州市地铁某暗挖隧道段基坑的地质情况和施工要求,制定了车站基坑监控量测方案,并对地表下沉,地表建筑物下沉及倾斜,暗挖隧道拱顶下沉,暗挖隧道净空水平收敛,钢拱架钢筋应力及爆破震动效应进行了监测分析,以便及时掌握开挖支护期间结构的稳定性及施工期间对周围环境的影响。
According to the geological situation and the demand of the construction for the submarine tunnel in Guangzhou subway, the scheme of supervision and measurement for station excavation is made. Surface subsidence, inclined and subsidence of surface buildings, vault crown settlement and horizontal clearance convergence of mined tunnel, steel stress and blasting vibration effect of the steel arch is monitoring analyzed, so as to timely grasp the stability of the structure during excavation and the impact of construction on surrounding environment.
