| 摘 要： | 高压旋喷桩是公路进行软基处理的一种有效形式。该文结合某高速公路软基处理实例,探讨了高压旋喷注浆法加固地基的机理,通过数值模拟对设计方案进行分析计算,重点分析了随上部逐级加荷,地基中的沉降变化,以及有无褥垫层对地基沉降及应力的影响。分析结果与工程的实测数据吻合较好。

| Abstract: | The high-pressure jet grouting pile is an effective method to treat the soft foundation of highway.Combined with a soft subgrade treatment of an expressway,the article discusses the mechanism of high-pressure jet grouting method to reinforce the subgrade.The numerical simulation is used to analyze and calculate the design scheme.The article focuses analysis on the settlement variety in the subgrade with the load applied step by step and the influence with or without cushion on the subgrade settlement and stress.The analysis result coincides well with the measured engineering data. |
