摘要
结合公路软土地基处治实践,分析CFG桩与高压旋喷桩多元复合地基加固效果。根据软土地基勘察结果,制定加固方案,并采用静载试验对单桩承载力和复合地基承载力进行检测,分析试验结果得出加固后地基承载力明显提高,加固效果良好。
Combined with the treatment practice of highway soft soil foundation, the reinforcement effect on the multiple composite foundation with the CFG pile and high pressure jet grouting pile was analyzed. According to the survey result of soft soil foundation, the reinforcement scheme was developed, and the bearing capacities of the single pile and the composite foundation were tested using static load test. The results showed that the bearing capacity of the reinforced foundation was significantly improved, which indicated that the reinforcement effect was good.
