饱和黄土的液化特性与稳态强度
|
摘要
通过应力控制固结不排水三轴试验,研究了饱和黄土的稳态强度特性及超固结对其不排水性状的影响。对比分析了黄土与砂土静力液化特性之间的异同。提出了饱和黄土流滑破坏的产生条件和利用稳态强度判断饱和黄土能否产生液化流滑的方法。
Steady state strength and undrained behavior of saturated loess are studied under stress-controlled undrained triaxial consolidation experiments. Static liquefaction behaviors of loess and sand are compared. Occurrence conditions of liquefaction for loess and the judgment method of flow slide of saturated loess by steady state strength are presented.
