| 摘 要： | 扬州六圩污水处理厂二期工程建设于地势平坦的河漫滩地,土层分布复杂,因污水处理工艺需要,需建设深度达9.05 m的粗格栅间和进水泵房。经方案比选,最终确定采用逆筑法进行泵房深基坑的开挖。详细介绍了逆筑法在这一特定土质条件及较小平面范围内实施较深基坑开挖的成功案例,并通过比较排桩及逆筑拱墙两种不同的支护形式,分析了逆筑法在支护工程中独特的优势。

| Abstract: | The second-stage project of Liuwei WWTP in Yangzhou City is located on a flat flood land with complicated soil layer distribution.Considering the requirements of wastewater treatment process,a coarse bar screen with depth of 9.05 m and an inlet pump room have to be built.The economic and safe excavation of deep foundation pit by the inverse construction method within limited flat space under the given soil condition is introduced.Through comparison between row piles and inverse arch walls,particular advantages of inverse construction method in shoring engineering are analyzed. |
