摘要
采用帽子模型对强夯时非饱和湿陷性黄土中的动应力分布进行了计算 ,计算结果与现场测试结果一致 ,证明帽子模型可作为非饱和黄土强夯动应力计算模型。通过对计算结果与实测资料的分析对比 ,对强夯法的加固机理作了进一步的探讨 ,最后得到了一些有益的结论。
In this paper, using the cap model as computing model, the distribution of dynamic stresses in unsaturated collapsible loess during dynamic compaction is calculated. The results calculated are consistent with the field measured results. It shows that the cap model used to calculate the dynamic stress is appropriate. Based on the comparison and analysis of theoretical calculation with the measurements, the stabilization mechanism of dynamic compaction is investigated and some useful conclusions are gained.
