| 摘 要： | 基于系统的试验 ,总结已有成果 ,研究了饱和黄土和砂土液化在液化机理、液化判别标准、影响液化的因素、孔压和应变的发展等方面的异同之处。研究表明 ,由于在液化机理上存在差异 ,导致二者动荷载下的孔压和应变发展特点有显著差别 ;同一因素对二者液化性状的影响可能相似 ,也可能不同 ;在动三轴液化试验中 ,黄土和砂土均可采用初始液化作为液化的判别标准。 |

| Abstract: | Achievements have been summarized through extensive experiments, which cover the liquefaction mechanism, criteria for liquefaction, factors influencing the liquefaction, and development of pore pressure and strain of saturated loess and saturated sand and the difference in between. The results of comparison show that due to difference of liquefaction mechanism, the development of pore pressure and strain under dynamic loading of both saturated loess and saturated sand are distinctively different. The impact of same factor on liquefaction performances of two might be similar and might not be similar. Initial liquefaction could be used as criteria for liquefaction for loess and sand in dynamic tri-axial liquefaction test. |
