摘要
根据株洲某基坑工程的地质条件、周边环境及基坑的设计深度,提出了螺旋锚支护方案,并对螺旋锚的抗拔承载力及支护结构进行了设计计算。计算结果表明:该支护方案对确保基坑稳定完全满足规范要求;同时,竣工后结算,采用螺旋锚支护方案与灌注桩方案的预算相比,节约了投资的50%,且不需进行砼养护,节省了工期。
According to geological condition of screw anchor in foundation pit engineering at Zhuzhou and the surrounding environment, it puts forward an project of screw anchor founding and calculates its anti-lift capacity and founding structure. The result shows that the project meets the requirement of its ensuring stability. As the foundation pit is adjacent to building, the scheme of the reinforced concrete pile had been considered before the screw anchor is used. After the finished engineering, 50 percent investment is saved, and time for a project is shortened.
