给水度与饱和差关系的初步研究

通过对给水度与饱和差的理论分析，明确了给水度与饱和差在基本概念上的差别；得出了饱和差通常是大于给水度而小于孔隙度，以及只有岩土体积含水率达到持水度时饱和差与给水度才相等的结论；给出了饱和差与给水度之间的定量关系式。这些结果得到了室内试验的验证。

Study on the Relation between Specific Yield and Saturation Deficiency

Through theoretical analysis,the differences in the basic concept between specific yield and saturation deficiency are specified;the conclusions are drawn that saturation deficiency is generally greater than specific yield and smaller than porosity and that only when the moisture content in the rock soil volume is equal to specific retention,saturation deficiency is equal to specific yield;the quantitative relation formula between specific yield and saturation deficiency is constructed.These results are verified with indoor experiments.
