利用中国建筑科学研究院地基所对碎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、实践中可行的计算方法。
Based on the model test results of the gravel pile foundations on the foundations of China Academy of Building Research, the different conditions of shear failure, piercing failure and bulging failure of the pile are analyzed. It is concluded that the foundation of the rammed pile composite foundation The most likely form of damage is shear damage. On this basis, the calculation model of the bearing capacity of the single pier of the dynamic compaction block is put forward, and the calculation formula of the bearing capacity of the single pier and the dynamic compaction block is deduced. Based on the calculated value and the on-site load The comparison of the test results proves the correctness of the model analysis results, which provides a theoretically reasonable and practically feasible calculation method for determining the bearing capacity of the rammed block composite foundation.
