振冲碎石桩在吹填软土地基中的应用

振冲法由交通部水运规划设计院（现中交水运规划设计院有限公司）与南京水利科学研究院于1977年协同引进我国，经过30余年的发展，得到了大面积的推广应用。通过工程实例，说明振冲碎石桩加固吹填软土（十字板小于20 kPa）取得了较好的地基处理效果，以期为类似工程提供借鉴。

Application of vibro-replacement gravel piles in hydraulic-fill foundation

The vibro-replacement gravel pile was first introduced to China by CCCC Water Transportation Consultants Co., Ltd. and Nanjing Hydraulic Research Institute in 1977, and has been widly developed and applied extensively during the past 30 years. This paper describes a successful project using vibro-replacement gravel piles for ground treatment in the hydraulic-fill foundation, which proves that the use of vibro-replacement growel piles for strengthening filled soft soil with undrained shear strength less than 20 kPa gets satisfactory results. Thus it may serve as a reference for similar engineering.
