《大型工程技术风险控制要点》对市政工程深基坑施工安 全的指导意义
摘要
In the process of urbanization and underground space engineering development, a large number of municipal deep foundation pit projects are concentrated in the city center, surrounded by buildings (structures), underground pipelines, etc., and the construction environment conditions are complex. Therefore, it is necessary not only to ensure the safety of the foundation pit itself, but also to strictly control the deformation of the surrounding soil caused by the excavation of the foundation pit to ensure the safety and normal use of the surrounding buildings (structures). This paper focuses on the risk factors analysis of the slope collapse of deep foundation pits in the "Key Points of Large-scale Engineering Technology Risk Control" compiled by the Ministry of Housing and Urban-Rural Development, and discusses appropriate risk control measures based on the risk factors.
