复杂环境及富水地质条件下的大型深基坑支护方案研究

Study on Support Scheme of Large and Deep Foundation Pit Under Complex Environment and Water-Rich Geological Conditions

以昆明市中区某大型深基坑为例,通过分析基坑周边环境、重点保护建筑、工程水文地质条件、基坑支护的重难点、不同基坑支护结构形式的优缺点及不同的适用范围等因素,同时根据基坑边界条件、昆明市本地环境保护政策和出土条件,提出了针对性较强的基坑围护施工方案,从而保证了基坑施工的顺利和安全。

Taking a large and deep foundation pit in the Shizhong District of Kunming as an example,by analyzing the surrounding environment of the foundation pit,key protected buildings,engineering hydrogeological conditions,the key and difficult points of foundation pit support,the advantages and disadvantages of different forms of foundation pit support structure,and different application scopes,etc.,at the same time,according to the boundary conditions of the foundation pit,the local environmental protection policies and unearthed conditions of Kunming City,the construction scheme of foundation pit support with strong pertinence is put forward,so as to ensure the smooth and safe construction of the foundation pit.
