| 摘 要： | 通过对经典的Priebe沉降计算法分析，以及面积置换率的变化对桩体压缩性假设作了改进；对桩土重度差异及承受荷载时应力和变形与深度的关系作了分析，归纳出相应的数学计算公式，用工程实例进行了验证。得到的结果表明改进是合理、适用的，可为今后的设计和施工提供参考。

| Abstract: | Based on the analysis of the classic Priebe settlement calculation method, assumption of stone column compressibility thuough replacement ratio change is improved. The bulk density differences of the stone column and soil and the relationship of the stress, deformation and depth under load stress are studied, and the corresponding coefficient formula deduced. Finally, the project is verified, the result shows the improvement is reasonable and can be a reference. |
