为了解决公路桥头跳车问题,采用 CFG 桩进行地基加固从而解决桥头跳车问题。通过实验研究和工程实例证明: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。
為瞭解決公路橋頭跳車問題,採用 CFG 樁進行地基加固從而解決橋頭跳車問題。通過實驗研究和工程實例證明:CFG單樁複閤地基中的褥墊層對于調整樁土荷載的分擔,減少承檯底麵的應力集中,進而保證樁土共同承擔荷載起著明顯的作用。

In order to solve the problem of abutment stag-gering on the road, CFG pile for foundation reinforcement is used. Experimental research and engineering examples prove that mat ress layer of CFG pile composite foundation plays an obvious role, which can adjust pile-soil load share and reduce the stress concentration of cushion cap bot om, so as to assume a shared load with piles and soil.
