碎石桩加强夯法处理软土路基的工程实践

Application of Soft Ground Formation by Gravel Pile and Dynamic Compaction

利用碎石桩加强夯法处理上部软弱、粘性含量高的软土地基,现场载荷试验和重型动力触探试验结果表明:该特殊工艺可充分发挥碎石桩对地基土体的挤密、预振、置换等作用和桩后强夯加强表层土体强度,提高复合地基的承载力,减少沉降。该方法经济有效、简单可行,完全满足设计要求。

Soft ground formation with high clayey soil and low surface layer soil quality is treated by gravel pile and dynamic compaction.According to static load test of pile and dynamic penetration test,the results,show treatment of settlement and bearing capacity of foundation soil is in the range of design.Gravel pile and dynamic compaction is economic and effective.
