To investigate the vertical strain development of sand under traffic loading after the process of ‘inclined’ consolidation, a series of cyclic drained tests were carried out by using a hollow cylinder apparatus. Three parameters were considered in this paper: initial consolidation angle, vertical cyclic stress ratio and cyclic torsional stress ratio. Test results show that the vertical strain under traffic loading path is larger than that of specimens whose cyclic torsional stress ratio is equal to 0 in the same situation. Furthermore, the vertical stain will decrease with the increase of consolidating inclination in the situation of same values of vertical cyclic stress ratio and cyclic torsional stress ratio. When initial consolidation angle is equal to 0° and 22.5°, the vertical strain will increase with increasing value of cyclic torsional stress ratio, while the effect of cyclic torsional stress ratio on vertical strain will be less significant when initial consolidation angle is equal to 45°. Moreover the trend that vertical strain increases with increasing value of cyclic torsional stress ratio will be more significant for a larger value of vertical cyclic stress ratio.

为了研究“倾斜”固结过程后交通荷载下砂土的垂直应变发展，使用空心圆柱体设备进行了一系列循环排水试验。本文考虑了三个参数：初始固结角，垂直循环应力比和循环扭转应力比。试验结果表明，在相同情况下，交通荷载路径下的竖向应变要大于循环扭转应力比等于0的试件。此外，在垂直循环应力比和循环扭转应力比值相同的情况下，垂直污点会随着固结倾角的增加而减少。当初始固结角等于0°和22.5°时，当初始固结角等于45°时，竖向应变将随着循环扭转应力比值的增加而增加，而循环扭转应力比对竖向应变的影响将不那么显着。此外，对于较大的垂直循环应力比值，垂直应变随循环扭转应力比值的增加而增大的趋势将更加明显。
