本文叙述了不同粒径的石英砂粒的物理力学特性与声速关系的室内试验研究,着重探讨了容重、含水量与纵波波速、横波波速之间的关系,给出了以含水量为参数的容重与纵横波速度间的关系式,以及空隙比与纵横波速度之间的关系式。此外分析了在各种不同含水量时,容重、空隙比与波速的单调变化关系,并给出了相应的表达式。
This paper describes the laboratory experiments of the relationship between the physical and mechanical properties of quartz sands with different particle sizes and the speed of sound. The relationship between bulk density, water content and the wave speeds of longitudinal and transverse waves, and the relationship between the velocity of shear waves and the bulk density are given. The relationship between the P-wave velocity and the relationship between the void ratio and the P-wave velocity. In addition, the monotonous relationship between bulk density, void ratio, and wave velocity was analyzed for various water contents, and the corresponding expressions were given.
