Slide breaking of shearing wedge block often occurs to elastic and plastic wall rockes around the circular roadways within the non-static head siress field in the direction perpendicular to its principal stress.

处于非静水应力场中的圆形巷道的弹塑性围岩常在其垂直于最大主应力的方向上产生剪切楔体滑移破坏。

Effect of variation of principal stress orientation during cyclic loading on undrained dynamic behavior of saturated loose sands.

主应力方向循环变化对饱和松砂不排水动力特性的影响。

It is based on the theory of spatial mobilized plane.

在目前的分析方法中，大多采用不考虑中主应力。。

To answer this question, we need to plot trajectories of principal stresses.

为了回答这个问题，我们尚须画出主应力迹线图。

According to research on space between wheel and Cart rut traverse curve of single roadway, the width of strip slab was fixed. When there was horizontal loading on slab, contact state between strip slab and base course was studied, and finite element model was established. Comparing maximum principle stress among different load position on slab, it was found that the critical loading position of cement concrete strips pavement was the middle of longitudinal joint.

对车辆轮距和单车道轮迹横向分布曲线进行分析，确定轮迹板板宽；在有水平荷载作用时，对轮迹板与基层的层间接触状态进行分析，建立有限元计算模型，对比荷载作用在轮迹板不同位置时的最大主应力，最终确定水泥混凝土轮迹路面板的临界荷位为纵缝边缘中部。

The results of numerical simulation indicate that the sand liquefaction is reflected by the accumulation of excess pore water pressure and progressive decrease in mean effective principal stress in macroscopic response; and on the other hand, corresponds to the cumulative loss of co-ordination number and continuous reduction of contact forces in microscopic fabric.

数值模拟研究结果表明，砂土液化现象在宏观力学表现上反映为超静孔隙水压力的累积上升和平均有效主应力的不断减小，在细观组构上对应于配位数的累积损失和粒间接触力的不断减小。

The fatigue limit of the S-N curve is found to be about 30% of the ultimate static failure stress, which validates the value suggested by the UK guidance.

其疲劳极限值约为静载作用下极限界面主应力的30%，与英国规程中的规定相符。

As a result of the relative difference in their velocities, polarized rays vibrating in planes of principal stresses S 1 and S 2 will emerge with a relative phase shift and produce color interference fringes or multicolored bands.

由于这一相对差，在其速度，偏振射线振动，在飞机的主应力s 一和S 2将会出现一个相对的相移，并产生彩色干涉条纹或彩色阶。

The region around the Ordos is divided into ten subregions based on neotectonic, geomorphologic and GPS data

在分区基础上，对各区的平均主应力轴分布进行了扫描，得到了其随时间的变化过程。

The orientation of the principal stresses relative to the directions of the polarizer a nd first quarter -wave plate is of course immaterial.

主应力相对于起偏镜和第一个四分之波片方向的方位，当然是无关紧要的。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
