| 摘 要： | 以自制的简易动力固结装置，对黄土的动力固结特征进行了初步的试验研究，重点探讨了土样在不同夯击次数下的力学参数变化规律。通过与各夯击次数对应的土样的定量化结构效应分析，初步掌握了动力固结过程的结构状态调整规律，并取得了最佳夯击次数的结构标志和相应的综合评价方案。

| Abstract: | With the boc consolidation instrument deveoloped by the authors , the features of dynamic consolidation of loess have been tested and studied preliminarily .As a key point ,the variation of mechnaical parameters under different compacting numbers is discussed and the relationships between dynamics stress and strain are identified .Through the quantitative microstructure analysis of the test samplescorresponding to different corresponding to different compacting mumbers ,the regularities of microstructure developement during the dynamic consolidation course have been known well, and the microstructure symbols realted to optimum compacting numbers and a scheme of comprehensive assessment is achieved. |
