在二维应力状态下,地震在土体中不仅产生动水平剪应力τνh,而且引起在一般情况下不可忽略的竖向动正应力σv及水平动正应力σh。
2.
The cyclic shearing stress induced by earthquake in earth includes cyclic normal stress difference, [σvd - σhd]/2, and horizontal tangential cyclic shearing stress, τhd These two componentS of cyclic shearing stress are the main factors complicating procedures for assessing the deformation or stability of earth and earth structures during earthquake.
在二维应力状态下,地震在土体中不仅产生动水平剪应力τhd,而且也引起在一般情况下不可忽略的竖向与水平动正应力差[σvd-σhd]/2,二者定义为动偏应力之二分量,均应是评估土体或土工结构物变形及稳定性的主要因素。

补充资料:刚体的平动
      刚体内任一直线在运动过程中始终同原来位置保持平行的运动,又称移动或平行移动。例如,在平直轨道上运行的火车车厢上任一直线,在火车运行过程中,始终同它原来的位置保持平行。平动刚体内所有各点在每一瞬时都具有大小相等、方向平行的速度和加速度,各点的运动轨迹也完全相同,互相平行。图中A1B1∥A2B2∥A3B3
  
  刚体作平动时,其内各点具有相同的运动,故刚体内任意一点(例如重心)的运动可以代表整个刚体的运动。因此,刚体的平动又可归结为点的运动学问题。
