摘要
对英安斑岩进行了声波波速测定,并测试了静力学参数,研究了英安斑岩的动弹性力学参数,建立了动静弹性参数之间的关系以及与波速的关系,并与已有结论相比较。研究结果表明,英安斑岩的密度和动弹性模量与纵横波波速有良好的线性相关性.其单轴抗压强度与声波波速有二次函数关系。最后,对岩石密度和声波波速之间具有的正向相关性关系的应用进行了讨论。
The acoustic wave velocity of daciteporphyry was measured,and its static mechanics parameters were tested also.The relationships between the dynamic and static elasticity parameters,and between the physical and mechanical parameters and acoustic wave velocity of the rocks were established,and compared with the anterior research results of other peoples.The research results showed that for daciteporphyry there is a good linear correlativity between the density or dynamic elastic modulus and the longitudinal or transverse wave velocity,there is relationship of quadratic function between the uniaxial compressive strength and the acoustic wave velocity.The applications of the positive correlativity between the density and the acoustic wave velocity were discussed.
