摘　　要： 抛石挤淤强夯置换施工方法,是在基底抛投碎石、块石等粗颗粒材料,将淤泥挤出,并对填石进行强夯使其密实并挤淤,以提高地基强度、降低压缩系数,满足工程建设需要的一种软基处理方法。本文以重庆市合川城区涪江上段防洪护岸工程(赵家渡段)为例,介绍一种适用于淤泥质高压缩性软土层地基水下抛石强夯基础的施工技术。 Replacement construction method of enrockment ground improved by dynamic compaction refers that gravels,stones and other coarse particle materials are thrown at the bottom for squeezing out sludge. The filled stones are dynamically compacted for making it compact and squeezing out sludge,thereby improving the foundation strength,reducing the compressibility,and meeting the needs of project construction. It is a soft foundation treatment method. In the paper,the flood prevention and bank protection project（ Zhaojiadu section） on the upper section of Fujiang River in Chongqing Hechuan District is adopted as an example. A construction technology applicable for muddy soft layer foundation underwater enrockment dynamic compaction with high compressibility is introduced.
