Through S-wave polarization scanning mode of ultrasonic impulse testing, rock samples with three different properties are measured to evaluate the variation of S-wave velocity in three perpendicular coordinates. By analyzing S-wave splitting of three directions and polarization of the maximum or minimum speed S-wave amplitudes, we think that the velocity orthotropy and fracture orientation observed in the grain sandstones and crack marble samples can be estimated in terms of the polarization and velocity of S-wave. Also, perpendicularity characteristics on the two types of rocks can attribute to the bedding and structure of rocks (directional grains or crystallize).

在实验室通过选择了三种不同岩性的岩石，采用超声脉冲测试方法中的横波偏振扫描方式，观测了岩石样品三个坐标方向上的横波速度变化，通过分析三个传播方向上出现横波分裂的差异，以及出现最大或最小快慢横波振幅的偏振方向发现，可从横波偏振方向和速度值判断出纹理砂岩和裂隙大理岩样品存在不同程度的速度正交各向异性和裂隙方向等特征，认为这两种岩石的正交特性的原因是岩石的层理或裂隙与岩石本身的结构构成的。

Their crack marksmanship and coordinated team maneuvers allowed them to outflank the Jedi trapped in the Temple, and mercilessly gun them down.

Conditions of the seepage and stress is a dynamic process, and also shows its interaction and interdependence. Owing to the closure of the fracture, the hydraulic gradient and the permeability pressure of the fracture turn large, and also promote the expansion of water cracks, and fissures connectivity increasing. The increase of the crack opening width will result in the increase of the infiltration capacity and seepage flow, and the reduction of seepage pressure. Because of the dynamic dependence of the fracture aperture, pressure and seepage, under certain conditions, changes in fracture aperture can lead to the formation of local water-passage, and the local emission of high pressure water, and thus promotes the formation of the sudden outgush disasters.

结果表明：洞室开挖完成后，在围岩渗流与应力耦合作用下，围岩中裂隙隙宽、裂隙中水压及其渗透流量的变化是一个动态过程，且相互作用与相互依赖；裂隙的闭合使得结构面水力梯度变大，作用在裂缝上的渗透压力增大，促进导水裂缝扩展，裂隙连通性增加；裂缝张开度增大，渗透能力增强，渗流量增大，其渗流压力相应降低；由于围岩中裂隙隙宽、压力和渗流量的动态依赖性，在一定条件下，裂隙隙宽的改变可导致局部水力通道的形成，高压水头从局部涌出，从而促进突水灾害的形成。
