摘要

本文在大三轴试验成果基础上

对在我国广泛采用的粗粒材料的E-μ模型存在的问题进行了分析。指出

模型中采用（σ1-σ3）f=R（σ1-σ3）ul的关系是多余的

反而给计算带来误差

模型中μi和σ3成半对数关系也不是唯一的。为了完善这个模型

作者建议了更适用的关系式。

Abstract

Based on the large-scale triaxial experimental resulte

some troublenesses in the E-μ model for big granular media widely used in our country are analysed . It is indicated that the relationship used in the model (σ1-σ3)f = R (σ1-σ3)u l is unnecessary and the semilogarithmic relationship between uf and σ3 is not unique. In order to inprove this model

a more convenient formula is suggested.
