高速公路工程软土路基应用振冲碎石桩加固分析

摘要

高速公路对路基沉降的要求很高，选择正确的地基处理方式直接关系到工程质量、投资和进度。本文对振冲碎石桩设计方法、施工工艺以及工程质量控制等进行了研究，并给出了振冲碎石桩在京珠高速公路软土路基加固中的应用实例。%Expressway has high requirements on the roadbed settlement, the right selection of foundation treatment way is directly related to the quality, investment and progress of the construction. This paper studies the design methods, construction technology and construction quality control of vibro-replacement stone column, and puts forward the application examples of vibro-replacement stone column of the soft soil subgrade reinforcement in Jingzhu Expressway.
