摘要
南通市新江海河闸是南通市五大引江口门之一,闸底板地基位于软弱地基,不能满足水闸对地基的要求。该文对该工程地质状况及方案比选进行了介绍,对工程施工中出现新情况后,采用水泥深搅桩结合沉管灌注桩进行地基处理方案,进行了详细阐述,并介绍了在设计中进行的承载力和沉降验算,同时,介绍了工程完工后的沉降观测,观测结果表明,复合地基满足设计要求,工程建成几年来运行可靠。
Xinjiang Haihe Gate of Nantong City is one of five large diversion gates in Nantong City. The ground of the gate bedplate is located at the weak subgrade,which can not meet the ground requirement of the water gate. The article introduces the geological status and the scheme comparison of the project. After the new condition presents in the engineering construction,the cement deep-agitating pile combined with the sinking pipe cast-in-situ pile is used to carry out the ground treatment scheme. The article sets forth in detail and introduces the bearing capacity and the settlement checking in the design. At the same time,the article introduces the settlement observation after the project is completed. The observation result makes clearly that the composite ground meets the design requirement. The operation is reliable for some years after the project completion.
