摘要
该文根据仙桃商城大厦西扩工程场地工程地质、水文地质条件及周边环境状况,同时考虑经济、技术、环保的条件下,选定采用灌注桩+内支撑的支护形式,支护桩外侧采用两排搅拌桩止水的综合手段对该基坑支护结构进行了设计,同时对钻孔灌注桩、水泥搅拌桩、内支撑、地下水处理、土方开挖等施工技术与施工要求做了详细的论述,对类似较为复杂的基坑支护结构设计与施工有一定的借鉴作用。
According to the conditions of engineering geology, hydrogeology and surrounding environment in west extending engineering of Xiantao mall, combining with economy, techniques and environmental protection, the foundation pit supporting design should be adopted as follows： cast-in-site pile with interior support, two rows water isolation mixing piles outside supporting piles. Construction technique and construction requirement of bored cast-in-site pile, cement mixing pile, interior support, groundwater treatment, and earthwork digging and so on are discussed in detail, they have some reference for similar foundation pit supporting design and construction.
