The results of numerical computations show that three main factors influencing the phenomenon are the permeability of the media, the porosity and the ratio of elastic wave impedance of the solid phase to that of the pore water, and that the frequency as well as the difference...

Based on the theory of wave propagation in porous, fluid-saturated media presented by the writer several years ago, the effects of dissipation and dispersion of seismic waves in water-saturated strata are studied in detail in this article. The results of numerical computations show that three main factors influencing the phenomenon are the permeability of the media, the porosity and the ratio of elastic wave impedance of the solid phase to that of the pore water, and that the frequency as well as the difference of compressibility between the solid grain and the solid skeleton do not have considerable effects. The effect of air or gas content in groundwater on the wave propagation is roughly estimated. Therefrom, it is pointed out that under some crustal and hydrogeological conditions there must be some error in the phase analysis in geophysics, in the explanation of data of seismic measurement in engineering seismology and in the treatment of dynamic problems of earth materials in geo-mechanics, where the water-saturated strata are regarded as composed of single-phased materials. Therefore, it seems necessary to consider the presence of pore fluids (water, air etc.) and make corresponding correction according to concrete situations.

根据笔者的饱和流体孔隙介质中波的传播理论,具体研究了地震波在含水地层中的耗散和弥散效应。数值结果表明,影响地震波在含水地层中传播的重要因素,除频率外,是固相骨架和水的弹性波阻抗的比值和介质的渗透性、孔隙率;而固相颗粒与固相骨架的可压缩性的差别因素则影响较小。估计了含气量对波传播速度的影响。指出了迄今在地球物理学中的震相分析,工程地震学中的测震结果的分析和解释,以及在地力学中处理动力问题时把含水地层按单相材料考虑都可能存在很显著的误差,需要考虑到孔隙流体(水,气)的存在和根据具体情况做些相应的修正。

The longitudinal elastic wave transmission through a coupling joint of two collinear semi-infinite beam structures is investigated by using wave theory approach.The joint is modeled as mass-spring system.Values for the vibration transmission and reflection efficiency may be obtained by using the one-dimensional wave equation and the idealized transition conditions of equilibrium and continuity at the joint.The vibration transmission and reflection efficiency are determined as functions of longitudinal elastic wave impedance and joint impedance,and their effects on transmission and reflection efficiency are analyzed.The results show the longitudinal elastic wave transmission through a coupling joint can be controlled to some extent by choosing the suitable impedance matching conditions between beam and joint.This study will enable one to properly use the correct vibration absorption and control technique,allowing systems to be designed for oprimal power transmission.
