| 摘 要： | 以佛山地铁1号线某盾构区间穿越沿线某建筑基坑锚索支护为背景,介绍了明挖基坑法、暗挖隧道法、套管拔除法和旋挖钻垂直切索法等4种对锚索支护的处理方案。综合考虑工期、工程造价、工程风险等因素,最终确定采用旋挖钻垂直切索法,取得了良好的处理效果。可为类似锚索清障工程提供参考。

| Abstract: | Based on the tunnel construction project of Foshan metro Line 1,which crosses through the existing deep anchoring cables of a building,4 kinds of anchor cable removing schemes——open excavation method,underground excavation method,casting extraction method and rotary drilling rig method——are introduced.Taking into account of the time limit,project cost and project risks,the rotary drilling rig method is finally adopted to deal with the anchor cable problems,which has achieved good results.This method can provide a reference for similar projects in the future. |
