劲性桩加锚杆在淤泥质软土深基坑中的应用

Application of Stiffening Pile and Anchor Rod in the Slope Protecion Work of a Deep Foundation Pit on Silty Clay Ground

芜湖世茂滨江花园工程基坑东西宽约106m,南北长约150m,开挖深度5.8～6.3m,场地内土质分布主要为杂填土和淤泥质粉质粘土。本文重点介绍了劲性桩的设计原理,施工流程、工艺和方法。通过在本工程的实际应用,我们发现该方法具有较好的支护效果,适用于多数工程地质条件的边坡支护,具有较高的推广应用价值。

The foundation pit in Wuhu Shimao Riviera Garden Project is 106m wide in east-west direction and 150m long in south-north direction and excavation depth reaches 5.8-6.3m. Miscellaneous fill and silty clay are distributed in the jobsite. This article focuses on the design principle, working process and know-how of the stiffening pile. Through the practical application, the slope protection method has reached the preferable supporting result, which is suitable for the side slope support and valuable to deploy in most engineering geological conditions.
