| 摘 要： | 在深入探讨块石墩复合地基承载机理的基础上，针对块石墩受力和变形特性，考虑墩周土体及其上作用竖向荷载对墩体极限承载力的影响，基于Vesic圆孔扩张理论，导出块石墩单墩体极限承载力计算公式，进而提出一种新的更为合理的强夯块石墩复合地基承载力计算方法。最后通过一具体工程实例，验证了方法的可行性。

| Abstract: | The bearing capacity of composite foundation which was formed by heavily rammed stone-piers was discussed in this paper. Then, based on the Vesic cavity expansion theory, an uhimate bearing capacity calculation method for single stone-pier is developed. This method can consider the influence on ultimate bearing capacity of stone-pier, which was caused by the surrounding soil and the vertical load on it. Finally, to validate the method proposed in this paper, a case history mentioned is illustrated. The calculation result of a case history shows that the calculated value is much closed to the observed value based on the method in this paper. |
