| 摘 要： | 桩土应力比是反映复合地基工作状态的重要参数，前人做了较多的理论工作，但理论解通常是在桩顶铺设砂垫层情况下推出的。在路堤荷载下浆固碎石桩复合地基一般在桩顶设置盖板，针对浆固碎石桩复合地基的特殊情况，进行了理论模型简化，并且运用极限平衡理论和弹性理论，推导了设置盖板的浆固碎石桩复合地基在路堤荷载下桩土应力比公式，并通过工程实测资料进行了验证，其结果可为浆固碎石桩复合地基的优化设计提供参考。 |
| 关 键 词： | 浆固碎石桩 盖板 极限平衡 桩土应力比 |

| Abstract: | The pile-soil stress ratio is an important parameter depicting the work state of composite foundation. Lots of theoretical researches were carried out in recent years; but they were usually deduced on the condition of laying sand cushion. Under the load from embankment, the capping plate is set at the top of grouting pile. Based on this especial condition, a proper theoretical model is brought forward. Furthermore, limit equilibrium theory and elastic theory are adopted to deduce the formula of pile-soil stress ratio of grouting gravel pile composite foundation under embankment load; and it is validated by project actual measurement and instruct the design of grouting gravel pile composite foundation. |
| Keywords: | grouting gravel pile capping plate limit equilibrium pile-soil stress ratio |
