摘　　要：该文介绍了在软土地区采用“气协法”进行沉管挤密碎石桩施工的特点及其优越性 ,它具有地基处理深度大、置换率高、桩体密度大、加固效果显著等特点 ,并通过工程实例进行了验证。The paper introduces the features of pipe sinking compacted gravel pile construction adopting the 'air-assistance' method and its superiority. It is characterized by the great depth of ground treatment, high displacement ratio, high density of pile body and notable solidification effect etc. All these are verified by practical engineering examples.
