Test results are as follows: Ballastless track structures can effectively improve the dynamic action of train loads on subgrade beds, the measured stresses and acceleration rates are far smaller than those measured with ballasted track structures; axle loads have remarkable influence on dynamic stresses of ballastless track subgrades and have some influence on acceleration responses; speeds of either motor car units or freight trains all have limited effect on dynamic embankment responses; after attenuating over 3 meters high embankment, neither dynamic stresses nor acceleration rates are influential to net cushions at the bottom of column-net structure subgrades

结果表明：采用无砟轨道结构可以有效改善列车荷载对路基基床的动力作用，测得的动应力与加速度值均远小于有砟轨道结构测得的值；列车轴重对无砟轨道路基的动应力影响明显，对加速度响应也有一定影响；无论是动车组还是货物列车，其运行速度对路堤部分的动响应影响均有限；动应力与加速度经3 m 高的路堤后衰减，对桩网结构路基下部的网垫层已基本无影响。

The aorta lies just to the left of the midline atop the lumbar vertebrae, ending at approximately the lower portion of the fourth lumbar vertebral body, where it bifurcates into the two common iliac arteries.

在腰椎体的上面主动脉就位于中线的左侧，主动脉约在第四腰椎体的下部终止，分支为两条髂总动脉。

The fold cambers in plane which protrudes to the south. Regional tectonic pattern show bigger hiberarchy, which mainly is composed of roof -slippage-fault-fold. The tectonic pattern of shallow hiberarchy which includes middle-upper Triassic's fragmentary rock is fault-propagation and low-angle faults fracture, its roof rock is mainly pelyte. The tectonic pattern of midding-deep hiberarchy which includes upper Paleozoic's carbonatite is possibly thrust and broad-tempered fold.

研究区的构造样式表现出较大的层次性，总体为盖层滑脱式逆冲褶皱型，其中，以中、上三叠统碎屑岩为主的浅层次，其构造样式主要为紧密型断滑或断展褶皱低角度逆冲断裂，其滑脱面为三叠系下部泥质岩或粉砂质泥岩；以上古生界碳酸岩为主的中深层次，其构造样式推测以冲断和宽缓褶皱为主。

Methods Take the height of a centrum and a clearance between two centrums as a standard metrical unit.
