| 摘 要： | 为解决高速公路桥头跳车问题,现对CFG桩进行地基加固分析,并通过工程实例进行实际验证,结果表明,CFG单桩复合地基中的褥垫层对于调整桩土荷载的分担,减少承台底面的应力集中,进而保证桩土共同承担荷载起着明显的作用,是保证CFG桩桩体与桩间土形成复合地基的一项重要措施。

| Abstract: | To solve the problem of bumping at the highway bridge-head,CFG pile was foundation strengthening analyzed,and was practical certified by engineering practice.The results show that cushion in CFG single pile complex foundation has obvious effect on adjusting sharing of pile-soil loading,reducing stress concentration of bearing station bottom surface,and ensuring pile and soil all bearing load,which is an important measurement of ensuring pile and soil between piles of CFG pile forming complex foundation. |
