The paper explores the treatment of the weak foundation according to the problems on consolidation of loss soil,the improvement of the soil compactness and the strength,and reduction of the compressibility,and introduces the development of the current foundation treatment by combining with the vibro-replacement stone,the deep dynamic compaction inside pile hole,the cement fly-ash gravel pile,and replacement cushion method,so as to provide the direction for the selection of the treatment method of the soft soil foundation.%针对如何加固松散土体,使土的密实度和强度提高、压缩性减小等问题,对软弱地基处理进行了探讨,结合振冲碎石桩、孔内深层强夯法、水泥粉煤灰碎石桩、换土垫层法介绍了当今地基处理的发展概况,为软土地基处理方法的选择提供了指导。
