| 摘 要： | 本工程位于荆州市沙市区北京中路与公园路之间,距离长江大堤较近,地层相对软弱,周边环境复杂,安全性要求高。通过分析和判断,决定采用明挖顺做法,经过方案比选总体上选择了两种支护方式结合的方案,双排桩、钢筋混凝土内支撑结合排桩支护方案。在工程实践中表明,根据实际情况所设计的基坑支护方案,最大限度地方便了基坑的开挖,而且可以做出最适合的支护方案,为今后的基坑设计提供了宝贵的经验。

| Abstract: | This project is located between Beijing middle road and park in shashi district of Jingzhou city.It is close to the Yangtze river embankment.The stratum is relatively weak,the surrounding environment is complex,and the safety requirement is high.Through analysis and judgment,it was decided to adopt the open-cut method.Overall,the scheme combining two kinds of support methods was selected through scheme comparison,namely,double-row pile and reinforced concrete inner support combined with row pile support scheme.In the engineering practice,it is shown that the excavation of the excavation pit to the greatest extant,and the most suitable support scheme can be made,which provides valuable experience for the design of the excavation pit in the future. |
