摘要
该工程周边环境条件复杂,施工操作空间有限,开挖深度约14.3 m,根据本地经验,一般采用钻孔灌注桩+三道钢筋混凝土内支撑的支护形式。文中设计方案结合工程地质及环境条件,对上部土层进行放坡,采用钻孔灌注桩+2道钢筋混凝土支撑的支护形式,有效减少了施工工期及成本。
The engineering environment condition is complex,the construction operating space is limited,the excavation depth is about 14.3 meters,according to local experience,we generally use the bored piles and three supporting form of reinforced concrete brace.In this paper,we design combined with engineering geological and environmental conditions,slope of upper soil layer,using bored piles and two reinforced concrete supporting form of support,effectively reduce the construction time limit and cost for the project.
