应用量纲分析方法建立了黄土地基强夯地面变形和夯后地基性状的量纲方程。利用有关工程实测资料,建立了强夯地面变形及夯后地基性状估算的最佳拟合方程,包括:强夯时夯坑深度及场地平均夯沉量与土质参数和施工工艺参数之间、强夯后部分土性指标与施工参数和夯前土质条件之间、夯后部分土性指标与夯击时地面变形和夯前土质条件之间的方程。最后,用若干实例对所建立的方程进行了验证;结果表明,计算结果与实测结果较吻合。方程的建立为夯前定量预估黄土地基强夯时的地面变形和夯后土性提供了一种实用途径。
Based on the method of dimensional analysis, a dimension equation of ground compaction and dynamic compaction of loess foundation is established. Based on the measured data of the project, the best fitting equation of dynamic compaction ground deformation and character estimation of rammed foundation was established, including: the depth of ramming pit and the average amount of compaction and settlement of the site with soil parameters and construction process parameters After the rammer between some of the soil properties and construction parameters and rammer soil conditions, between the rammer after some of the soil properties and the impact of the ground deformation and rammer soil conditions between the equation. Finally, some examples are used to verify the established equations. The results show that the calculated results are in good agreement with the measured ones. The establishment of equations provides a practical way for quantitative prediction of ground deformation and soil properties after dynamic consolidation in loess foundation.
