复杂环境下深基坑内旧地下室的拆除设计与施工

Demolition Design and Construction of Old Basement in Deep Foundation Pit Under Complex Environment

针对周边环境复杂的深基坑内既有地下结构的大范围拆除施工,在综合考虑周边环境的情况下,提出了相应的地下室拆除设计方案与施工关键技术。相关施工方案在减小基坑变形的同时,也减少了对周边环境的影响,总结的施工经验可为类似工程提供借鉴。

In view of the large-scale demolition construction of the existing underground structure in the deep foundation pit with complex surrounding environment,the corresponding basement demolition design scheme and construction key technology are put forward under the comprehensive consideration of the surrounding environment.The construction scheme not only reduces the deformation of foundation pit,but also reduces the impact on the surrounding environment.The construction experience summarized can provide reference for similar projects.
