摘要基于弹性波在冻结饱和多孔介质与单相弹性介质中的传播理论，选取了饱和冻土中传播速度最大的快压缩P1波入射在饱和冻土与弹性基岩分界面上的能量传输问题。根据分界面上的边界条件，推导出了快压缩P1波从饱和冻土介质入射到弹性基岩分界面上透反射振幅比和能量率的解析表达式。研究了快压缩P1波入射在饱和冻土与弹性基岩分界面上的能量与入射角度，入射频率，温度（含冰量），孔隙率，胶结参数以及接触参数的关系。研究结果表明：当入射角度为0时仅存在压缩波，达到临界角后透射P波消失；各种波在达到临界角时出现不同程度的脉冲，其中反射P1波最为显著；随着胶结参数，孔隙率，接触参数的增大，临界角越早出现；入射频率仅对反射P2，P3和S2波的能量反射率影响较大；当温度和含冰量较低或较高时，均不利于反射S2波的能量产生。

Abstract：Based on the propagation theory of elastic waves in frozen saturated porous media and single-phase elastic media, the energy transmission problem of the fast compressional P1-wave with the maximum propagation velocity in saturated frozen soil was selected at the interface between saturated frozen soil and elastic bedrock. According to the boundary conditions at the interface, the analytical expressions of transmitted and reflected amplitude ratio and energy ratio of the fast compressional P1-wave from saturated frozen soil to elastic bedrock are derived. The incident energy relationship of fast compressional P1-wave at the interface between saturated frozen soil and elastic bedrock with incident angle, frequency, temperature (ice content), porosity, cementation parameter and contact parameter is studied. The results show that there is only a compression wave when the incident angle is 0, and the transmitted P wave disappears after reaching the critical angle. Various waves have different degrees of pulses when reaching the critical angle, among which the reflected P1 wave is the most significant. As the cementation parameters, porosity and contact parameters increase, the critical angle appears earlier. The incident frequency only greatly influences the energy-reflected ratio of reflected P2, P3 and S2 waves. When the temperature and ice content are low or high, it is not conducive to the energy generation of reflected S2 waves.

Key words： saturated frozen soil elastic bedrock fast compressional P1-wave transmitted and reflected amplitude ratios transmitted and reflected energy ratios
