A constitutive equation for 2-dimensional non-linear dilatancy model and the effect of SUBCRUSTAL rock dilatancy on the verticle displacements at the surface of the earth 二维非线性膨胀模型及壳内膨胀体对地表垂直位移的影响
Based on the research on pore pressure in saturated soft soils, this paper presents a shear dilatancy model considering the effect of cementation of soil and then focuses on the effect of cementation on pore pressure in saturated soft soils. 在前人对孔隙水压力研究的基础上,提出了考虑土颗粒之间胶结特性影响的土体剪胀模型,并应用该模型分析了土体结构性对孔隙水压力的影响。
In this paper, it was proposed the dilatancy occurred in soil mass is a second power effect of applied deviator stress. 本文认为土体的剪胀性是偏应力的二次幂效应。
A comparative study was made for the current solution and the solution based on elastic-perfectly plastic model in order to analyse the effect of soil dilatancy and strain-soften. The result indicated that the effect of the strain-softening and the shear dilatation were Significant. 为了反映剪胀和软化特性对柱形孔扩张的影响,将本研究解与基于理想弹塑性模型的解进行了比较分析,结果表明,剪胀和软化特性对孔扩张影响显著。
Non-uniform shear dilatancy of rock specimen due to plastic shear strain localization is analyzed considering strain gradient effect. 采用梯度塑性理论,对岩样剪应变局部化引起的扩容进行了理论分析。
