成都地区常见深基坑支护措施及其运用的探讨

Discussion on supporting measures and application of common deep foundation pit in Chengdu area

在分析成都地区工程地质条件的基础上,结合涉及基坑安全的周边环境的分析,初步总结了目前成都地区常用的基坑支护手段,以某建筑场地的基坑支护工程为实例,在分析场地工程地质条件及周边环境基础上,分析了常用的基坑支护手段,以及在膨胀土地区深基坑支护设计中综合运用支护合成组合法的工程应用实例,做到信息化设计与动态施工,确保基坑安全。本文可为成都地区基坑设计及施工提供类似的设计施工经验。

Based on the analysis of the engineering geological conditions in Chengdu area,combined with the analysis of the surrounding environment related to the safety of the foundation pit,this paper preliminarily summarized the commonly used foundation pit supporting means in Chengdu area at present.Taking the foundation pit supporting works in a construction site as an example,through the analysis of the ground quality conditions and the surrounding environment of the site engineering,this paper analyzed the commonly used foundation pit supporting means and introduced the expansion of the land in the design of deep foundation pit,the composite support combination method was used in the engineering application to achieve the information design and dynamic construction to ensure the safety of foundation pit.It can provide similar design and construction experience for foundation pit design and construction in Chengdu area.
