饱和砂土液化特性的可视化试验研究
Visualization testing on liquefaction properties of saturated sands
摘要
Abstract
Based on the C.K.C cyclic triaxial testing system a cyclic triaxial visible testing system was designed for studying the liquefaction behavior of saturated sands at the meso-mechanical level.The cyclic triaxial visualization testing was performed on saturated sands.The meso-fabric characteristics of saturated sands were studied such as motion and macro-axis orientation for sand granules, average coordination number and porosity.The results show that, sand granules continuously rearrange and redirect for the new stress state under cyclic loading; then liquefaction occurs.And the study shows that the meso-mechanism of sand liquefaction can be analyzed by the cyclic triaxial visualization testing system for real-time visible liquefaction.关键词
