各向异性是岩土材料普遍具有的性质,而横观各向同性是岩土各向异性最通常的表现形式,因此在真三轴试验中,不同加荷方向下的大主应力方向与颗粒沉积方向之间形成的不同夹角(α角)对其本构特性影响的研究是具有意义的。在有效围压为200 k ...各向异性是岩土材料普遍具有的性质,而横观各向同性是岩土各向异性最通常的表现形式,因此在真三轴试验中,不同加荷方向下的大主应力方向与颗粒沉积方向之间形成的不同夹角(α角)对其本构特性影响的研究是具有意义的。在有效围压为200 k Pa,中主应力系数为0,0.5,1的条件下,采用不同的制样方法,分别进行α角为0°,60°,90°的饱和粗砂进行排水剪切试验,并结合试验数据探究其应力应变及剪胀特性。最后,通过分析似临界状态下有效球应力p′–偏应力q曲线和lnp′–孔隙比e曲线,得出不论α角取何值,其临界状态都是存在的。展开更多
