| 摘 要： | 以河北省非饱和原状土和重塑土为对象,采用常规三轴不固结不排水试验,对不同含水量土样的抗剪强度参数进行了测定,探究土样含水量与抗剪强度参数的关系.证明了含水量对非饱和土的粘聚力有较大的影响,而与内摩擦角的关系不明显,并且内摩擦角有随含水量增加而减小的趋势.这一研究成果加深了工程师对非饱和土的认识,方便了非饱和土研究在工程中的应用.

| Abstract: | By unconsolidated-undrained triaxial tests of unsaturated soil with remolded soil samples and undisturbed soil samples in Hebei province, relationship between water content andshearstrength parameters of unsaturated soilisstudied. The results show that the change of water content has great effect on cohesion but little on inner frictional angle, which has decreased trend with the increase of water content of unsaturated soil. The relationship enhances our cognition on un- saturated soil and makes it easier for engineers to apply the study results of unsaturated soil to engineering practice. |
