principal stress axis

基本解释

Clearly, characteristics of shear failure and failure criterion in stress path for rotation of principal stress axis were one of the important issues related to practical engineering design.
显然，主应力轴旋转路径下土体的剪切破坏特性及破坏标准是实际工程设计关注的重要问题之一。
The fault plane solution shows that the fault is thrusting towards the south, the principal compressional stress axis being in general directing either N-S or NE and relating to the focal depth.
断层面解表现为向南逆冲，主压应力轴基本上为南北向和北东向，且与震源深度相关。
In order to study the influence of principal stress axis cyclic rotation at low shear stress level on clay′s behavior, a series of experiments of Hangzhou typical intact soft clay were conducted.
为研究低剪应力水平主应力轴循环路径可能对黏土性状产生的影响，以杭州地区典型原状软黏土为对象开展试验研究。
