盾构下穿建筑物施工控制要点

Shield construction control points of penetrating beneath buildings

在城市地下进行盾构隧道掘进施工,有时会不可避免地下穿建构筑物或地下管线。本文根据工程实例,通过采取土压力控制、渣土改良、掘进参数控制、监测控制、工后处理等各种技术、安全措施成功地穿越了四栋建筑物,希望对相同或接近地层的盾构施工起到借鉴作用。

In the construction of city shield tunneling underground, sometimes penetrating underground building structures or underground pipelines is inevitable. Based on practical projects, by taking a variety of techniques and safety measures to control soil pressure, sediment improvement, tunneling parameter control, monitoring and control, post -processing, 4 buildings have been suceesstully penetrated through. It is hoped to provide a referenc, e for the same or similar shieht construction.
