摘　　要：引江济淮工程是一项国家级重点水利工程项目,基坑的施工处理是整个引江济淮工程的基础,合理的基坑处理也是该工程建设的关键。本文对引江济淮工程中枞阳引江枢纽进行了概述,并对工程地质情况、存在的问题以及相应的基坑处理方法进行了介绍,重点阐述了如何确定双向水泥土搅拌桩的施工参数以及具体的施工工艺,并根据实际施工情况提出质量控制措施。文中内容可为类似工程中采用双向水泥土搅拌桩进行基坑处理提供经验。Water Diversion from Yangtze River to Huaihe River Project belongs to a key national water conservancy project.The foundation pit construction treatment is the basis for the whole Water Diversion from Yangtze River to Huaihe River Project. Zongyang water diversion hub in Water Diversion from Yangtz River to Huaihe River Project is summarized in the paper. The engineering geological situation, the existing problems and corresponding methods for the treatment of foundation pits are introduced. How to determine the construction parameter of the bidirectional cement-soil mixing pile and concrete construction technology is mainly described. Quality control measures are put forward according to the actual construction situation. The paper can provide experience for similar projects to apply two-way cement-soil mixing pile in foundation pit treatment.
