将史宏彦等提出的无粘性土的应力矢量本构模型应用于分析多种复杂应力路径下材料的变形问题· 结果表明 ,此模型不仅能够很好地反映无粘性土的应力应变非线形、硬化性、剪缩剪胀性、与应力路径的相关性、主应力与主应变增量方向之间的非共轴性以及球偏应力与变形的耦合性等主要变形特性 ,而且也能够同时考虑主应力轴的旋转和中主应力对土的变形及强度的影响· 模型预测结果与试验结果之间的良好吻合表明了该模型的广泛适用性
Based on the analysis of the forces acting on the fine grains in the skeleton pores,a capillary-tube model is introduced to characterize the development of piping in noncohesive soils.
通过对骨架孔隙中细颗粒的受力分析,建立了描述无粘性土中管涌发生、发展的毛管模型。
In this paper, the grains of piping-typed noncohesive soils are classified into three groups: skeleton, movable and clogging.
将管涌型无粘性土中的颗粒分为骨架颗粒、阻塞颗粒和可动颗粒三组,在分析骨架孔隙中可动颗粒受力的基础上,将总压力降分为骨架孔隙壁引起的压力降、骨架孔隙中静止颗粒引起的压力降及正在运动的颗粒引起的压力降三部分,从而得到了可动颗粒起动的临界水头梯度公式。
