在围压下岩石弹性波速的研究

Study on Elastic Wave Velocity of Rock under Confining Pressure

本文介绍在单轴和三轴压缩下岩石的纵波波速、横波波速、动弹性模量、动剪切模量和动泊松比及强度等物理力学参数的变化规律及其与力学特性的关系,同时综述一定围压下温度对岩石弹性波速的影响。

In this paper, the physical and mechanical parameters of rock including velocities of longitudinal and shear waves, dynamic elastic and shear moduli, dynamic poisson's ratio and strength, etc., and also the variation of these parameters in the course of uniaxial and triaxial compressive loading and their relationship with mechanical characteristics are introduced. In the meantime, the effect of temperature on elastic wave Telocity of rock under given confining pressure is comprehensively reviewed.
