The result shows that, under the condition of the same thickness of material, increasing the number of layers properly can weaken the press, the cutting damage and the destruction due to extension, and lower the impact energy on the construction effectively. In particular, multi-layered protection construction is rather striking in its advantage of destruction-resistance under high stress and low impulse load.

The plastic deformation induced due to cyclic rotation of principal stress axes alone can be in the same magnitude as that due to shear with fixed principal stress axes. 2 The volumetric strain due to shearing of cyclic rotation of principal stress axes is found to be composed of a reversible dilatancy component and an irreversible dilatancy component. The former is characterized by its reversibility and is independent of past shear history, the latter by its irreversibility increases with the increase of cycle number yet its increase rate decreases with its accumulation. 3 The obvious non-coaxiality between directions of the principal stresses and principal strain increments is found and its degree depends largely on the change of shear stress component. 4 The intermediate principal stress has considerable effects on the deformation behavior of sands in the condition of cyclic rotation of principal stress axes. The accumulation rate of the irreversible dilatancy component increases with the increase of the intermediate principal stress parameter.
具有初始各向异性的砂土在纯应力主轴循环旋转排水条件下的主要变形规律为:①纯应力主轴循环旋转可产生与应力主轴固定单调剪切处于同一数量级的塑性变形;②纯应力主轴循环旋转引起的剪切体变包含可逆性剪切体变分量和不可逆性剪切体变分量两部分,其中可逆性剪切体变分量在一周内可完全恢复,基本与应力历史无关;不可逆性剪切体变分量随循环周数的增加呈单调增加,且增加速率随其自身累积值的增大呈减小趋势;③应变增量主轴与应力主轴之间的非共轴现象显著,且在一周内具有分段性;④中主应力对应力主轴循环旋转条件下砂土的变形特性有重要影响,不可逆性剪切体变分量的累积速率随中主应力系数的增加而增加。

First, based on the analysis of the grid Reynold number, the necessity for adopting high order scheme is emphasized when there is the complex flows with strong separation and high parameters gradient regions. Then, according to the entropy increased condition, the third order ENN scheme is constructed. Meanwhile, a fast, effective, and simple implicit numerical method called hybrid flux splitting method is developed. After that, the one dimensional model problem with many extrema and Burgers equation are simulated. Through the comparisons with exact solutions, the accuracy and effectiveness of the ENN scheme are confirmed.
