川东北飞仙关组岩石动力特性的试验

Experimental research on dynamical characterristics of rock in fei xianguan northeast in sichuan

以川东北飞仙关组岩石(砂岩、灰岩)为实验试件,利用自行设计的声波测试装置,应用声波测试技术对川东北飞仙关组岩石的动力特性进行了室内试验研究,测出了岩石试件的弹性波速(纵波波速Vp、横波波速Vs),并获得该类岩组的一系列动弹性参数(动弹性摸量Ed、动泊松比υd、动剪切模量G、动体积模量K)。并根据试验结果分析了岩石的物理力学性质。结果表明,该实验的原理和方法可为相关工程所利用。

Rock(sandstone, ash stone) in fei xian guan northeast Sichuan was used as rock sample,Experimental research on elasticity wave in room was done by testing technology of sound wave. The speed of elasticity wave and the dynamical elasticity parameter is calculated by the experiment. After the experiment, the physics mechanic character of rock is analyzed by experiment data.
