摘要
利用人工制备结构性土样进行多组常规三轴试验,重点探讨排水条件对结构性土体破损过程和剪切带形成过程的影响。试验结果表明,不排水条件会减缓弱胶结结构性土的破损,从而加速强胶结结构性土的破损,进而影响土体的变形破坏过程以及剪切带的形成过程。
A series of conventional triaxial tests on artificial structured soil samples were carried out to investigate the influence of drainage condition on the breakage of samples and the formation of shear band.The test results show that the undrained condition would slow down the breakage of weak-banding structured soil and speed up the breakage of strang-bonding structured soil,which finally influences the failure process of soil samples and the formation of shear band.
