【摘要】 以海南省文昌市文东路二期B标段工程为例,按照现行设计规范提供的不良路基处理方法及相关计算公式,并结合工程投资,对CFG桩与碎石桩两种针对较厚软土层的路基处理方案进行了比较分析。CFG桩处理效果优于碎石桩;CFG桩单价较高,但对于较厚的软基,经济效果更优。该工程经处理后,路基压实度及弯沉值均达到规范设计要求,使用效果良好。更多还原

【Abstract】 Taking Hainan Province Wenchang City Wendong Road Phase II Tender Section B Project as an example, according to the bad roadbed treatment methods provided in the current design code and the relative calculation formula, and combined with the engineering investment, this paper compares and analyzes the roadbed treatment schemes of CFG pile and gravel pile in the thick and soft soil stratums. The treatment effect of CFG pile is better than the gravel pile. The unit price of CFG pile is higher, but the economic effect is more excellent for the thicker soft foundation. The roadbed compactness and deflection value of this project all meet the standard and design requirements after treated. And the service effect is good.更多还原
