摘要
本文结合目前国内外砂土剪胀理论前沿课题,以饱和砂土的剪胀机理及本构模型为研究对象,通过大量的固结不排水(CU)和固结排水(CD)三轴试验,对基于材料内部状态的饱和砂土剪胀性本构模型进行了试验验证.
This paper, taking account of the cutting-edge topics of the current international and domestic sands dilatancy theory and taking the dilataney mechanism and the constitutive model of saturated sands as the subject of research, carries out a large number of consolidated undrained （CU） triaxial tests and consolidation drainage （CD） triaxial tests. A test and verification of the dilatancy mechanism and the constitutive model of saturated sands, based on the internal condition of the material is conducted.
