matric suction

基本解释

Matric suction is a very important concept in unsaturated soil mechanics, and it is not easy to understand its physics significance.
基质吸力是非饱和土力学中一个非常重要的概念，也是初学者学习中的一个难点，要把它理解透彻并不容易。
As a result, the research on the relationship among water content and matric suction and the soil strength are of value to civil engineering projects.
因而，研究含水量与基质吸力和边坡土体强度的变化规律都具有很重要的工程意义。
Experimental results showed that the resilient modulus of unsaturated cohesive subgrade soils reduced with the increase of deviator stress and the decrease of matric suction.
研究结果显示重复荷载下之偏应力愈大则回弹模量愈小，且回弹模量随基质吸力的增加而增加。

基质吸力
An extended Mohr Coulomb failure criterion is used to allow for shear strength variations as a result of changes in matric suction. Effects of various rainfall events, hydrogeological conditions and use of protective cover on the cut slope are investigated.
计算中采用延伸的摩尔-库伦破坏准则以便考虑基质吸力对抗剪强度的贡献，研究了降雨特征、水文地质条件及坡面防渗处理等因素对暂态渗流场和斜坡安全因数的影响。
