| 摘 要： | 利用中国建筑科学院地基所对矿石桩进行的模型试验结果，分析了散体桩（墩）发生剪切破坏、刺入破坏和鼓胀破坏的不同条件，得出强夯块石墩复合地基最有可能的破坏形式为剪切破坏。在此基础上，提出了强夯块石墩单墩承载力计算模型，推导出了强夯块石墩单墩和强夯块石墩复合地基承载力的计算公式，并通过计算值与现场荷载试验结果的对比，验证了模型分析结果的正确性，从而为强夯块石墩复合地基承载力的确定提供了理论上合理、实践中 |

| Abstract: | The bearing capacity calculation is an important design content for composite foundation by tamping stone piles.We analysed different conditions for shallow sheared destruction,sticked destruction and inflated destruction of bulk stone piles using the model testing results by Foundation Branch of China Construction Institute,and considers that the most possible destruction formation is shallow sheared destruction.The paper abstracts calculation model of single stone pile bearing capacity and derives the calculation equations of both single stone pile and composite foundation by tamping stone piles.The paper also verifies the correctness of the calculation equations by field loading test result;therefore a method of composite foundation by tamping stone piles bearing capacity calculation is ascertained. |
| Keywords: | tamping stone piles composite foundation bearing capacity |
