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 engineering geology, hydrogeological conditions and the surrounding environment of West Xiantao Site of Xiantao Mall, considering the economic, technical and environmental conditions, the supporting form of bored pile and internal bracing is selected. The outside of bracing pile is adopted Two rows of mixing pile water stop the comprehensive means of the support structure of the foundation pit design, at the same time on the bored pile, cement mixing pile, internal support, groundwater treatment, earthwork excavation and other construction techniques and construction requirements detailed Discussed, similar to the more complex structure of the foundation pit support design and construction have some reference.
