粗粒土剪胀特性研究现状与趋势
Status Quo and Tendency of Studies of Dilatancy of Coarse-grained Soils
摘要
Abstract
This paper provides a review of the research progress on characteristics of dilatancy of coarsegrained materials,including influencing factors,mechanism of dilatation,equation of dilatation and constitutive model etc.Based on discussion of problems in the research,it is pointed out that turther research should focus on the following aspects:Studying the existence of critical state of coarse-grained soils and giving a quantitative description.Further researching the characteristics of dilatancy which is relative to the state based on considering the influencing factors such as particle breakage and determining the reasonable state parameters.And then,establishing the equation of dilatation which is suitable to the coarse-grained soils.Building reliable and effective constitutive model of coarse-grained soils based on the equation of dilatation.关键词
