摘要
通过动扭剪试验研究饱和粉煤灰的动孔隙水压力特性、动强度特性以及振陷变形特性。饱和粉煤灰在动扭剪试验过程中,随着轴向变形的发展,孔隙水压力呈双曲线型逐渐上升,饱和粉煤灰的动强度及变形特性与饱和黄土非常相似;同时,分析干密度、固结应力对粉煤灰动力特性的影响。
Some behaviors of saturated flyash such as pore water pressure,dynamic strength,and dynamic deformation are studied by the dynamic torsional shear test.The pore water pressure gradually rises with the development of axial strain in the process of the dynamic torsional shear test,but it essentially keeps constant or goes up a little in the latter stage.There are some considerable similarity in strength and strain between saturated flyash and saturated loess.The effects of dry density and consolidation pressure on the dynamic characteristics of flyash are also analyzed.
