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。
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。
Matric suction is relevant with temperature of water-air system, density of pore-water, and relative humidity of pore-air of unsaturated soil.
非饱和土的基质吸力与其中水—气体系的温度、孔隙水的密度和孔隙气的相对湿度有关。
