matric suction

基本解釋

Matric suction is a very important concept in unsaturated soil mechanics, and it is not easy to understand its physics significance.
基質吸力是非飽和土力學中一個非常重要的概念，也是初學者學習中的一個難點，要把它理解透徹并不容易。
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，研究含水量與基質吸力和邊坡土體強度的變化規(guī)律都具有很重要的工程意義。
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.
研究結果顯示重復荷載下之偏應力愈大則回彈模量愈小，且回彈模量隨基質吸力的增加而增加。

基質吸力
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.
計算中采用延伸的摩爾-庫倫破壞準則以便考慮基質吸力對抗剪強度的貢獻，研究了降雨特征、水文地質條件及坡面防滲處理等因素對暫態(tài)滲流場和斜坡安全因數的影響。

基質吸力
The flow of water through unsaturated soil is primary a function of matric suction and gravity.
非飽和土中水流的驅動勢為基質吸力和重力。
