邻近建筑物被动区预留加固软土换撑地下车库深基坑施工技术

Construction Technology of Retaining Reinforcing Soft Soil and Supporting for Deep Foundation Pit of Underground Garage in Passive Area Adjacent to Buildings

针对邻近既有建筑物开挖深度范围为软土地质条件的城市公园地下车库基坑施工,支护开挖方案中究竟采用什么形式支护开挖工艺可以既节省工程成本,又能提高工效?论文介绍一种邻近建筑物被动区预留加固软土换撑地下车库深基坑施工技术,针对这种特点的地下车库深基坑施工,巧妙解决了邻近建筑物基坑开挖的稳定性问题。

For the construction of the underground garage foundation pit in the urban park near the existing buildings whose excavation depth range is soft soil,what form of support and excavation technology can be used to save project cost and improve work efficiency?This paper introduces a kind of deep foundation pit construction technology of soft soil replacement for underground garage in passive area of adjacent buildings.Aiming at the construction of the deep foundation pit of the underground garage with this characteristic,it ingeniously solves the problem of the stability of the foundation pit of the adjacent building.
