Application of circular reinforced concrete purlins in the small-size deep foundation pit in the loess area

  • 为解决周边环境条件异常复杂、无锚索施工空间、紧邻对变形异常敏感的多层建筑物的自重湿陷性黄土地区开挖尺寸小深度大的顶管工作井的难题,以西安市东郊某直径10.0 m,深度24.50 m的深基坑为代表,采用钢筋混凝土环形围檩替代传统的内支撑来抵抗土压力,既不影响狭窄空间的土方开挖,又很好的控制了围护结构的变形,保护了周边环境的安全。数例工程实践表明,在直径小于12 m,深度不大于25 m的圆形深基坑中,采用钢筋混凝土环形围檩体系,支护费用低、围护结构变形很小、周边环境安全可靠、土体中无锚杆(索)残留,对邻近地下空间后期开发利用无影响。项目的顺利实施为自重湿陷性黄土地区类似深基坑开挖提供了一种解决问题的思路,具有一定的借鉴意义。
