Effect of Strengthening Soft Foundation with Vibrating Sinking Tube Gravel Pile and Construction Process Analysis

介绍碎石桩加固原理,进行复合地基允许承载力及变形计算,提出振动沉管碎石桩设计注意事项,简要介绍碎石桩的施工质量控制要点。结合工程实例,详细多方面分析碎石桩加固砂性土和粘性土效果的差异及其原因。

This paper introduces gTavel pile strengthening concept, conducts eomplex toundation beating capacity and deformation calculation, suggests cares to be taken in vibrating sinking tube gravel pile design, as well as key quality control measures in grovel pile construction. It gives detail analysis to difference and reason between the effect of sand soil and cohesive soil in gravel pile strengthening from multiple aspects.
