摘要
随着基坑周边环境越来越复杂,开挖深度越来越深,同一个基坑根据不同的周边环境采用不同的支护形式也越来越普遍。以云南昆明市某城中村改造工程实例为研究背景,重点介绍以内支撑、桩锚、局部土钉墙等多种支护形式组合的深基坑设计和施工,为今后类似组合式基坑支护工程提供参考。
As the surroundings of the foundation pit becoming more and more complicated and the excavation depth becoming deeper and deeper, it is more common to use different supporting forms for the same foundation pit according to different surroundings. Taking a reconstruction project of one urban village in KunMing, Yunnan Province as an example, the paper highlights a multiple supporting form combined with the internal bracing, the pile-anchor and the partial soil- nailed wall in deep foundation pit design and construction, which can provide reference for future similar combination supporting engineering of foundation pits.
