the matric suction的意思|示意

The results show that the matric suction is lose on account of the rainwater infiltration;

分析结果表明：雨水入渗引起土壤基质吸力的大量丧失；

The stress-strain relationship depends on the combinational style of net normal stress and matric suction, and suction enhances the stress-strain stiffness feature during triaxial shear test.

在剪切试验中，非饱和黏土应力应变关系依赖于净围压和基质吸力的不同组合，基质吸力增强土体应力–应变关系的硬化特性；

Based on the field monitored results of volumetric water content and matric suction, field soil-water characteristic curves for the soils at different depths at the crest are determined.

根据土体体积含水量和吸力值的野外监测结果，得出了边坡坡顶土体不同深度的野外土-水特征曲线。

It is very difficult to resolve or measure matric suction in engineering practice, because the matric suction is not constant especially under undrained condition.

实际工程中求解和测定吸力比较困难，特别在不排水条件下，吸力并非常量，从而难以确定。

Furthermore, the tension suction, which was closely related with but rather different from the matric suction, was presented on the basis of thermodynamics.

然后基于热力学原理，提出了另外一个与基质吸力紧密相关而又不同的吸力概念-张力吸力。

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。
