| 摘 要： | 在Biot饱和多孔介质动力学理论的基础上，利用Fourier—Bessel级数展开法，得到SV波在饱和土半空间中圆柱形孔洞周边的散射问题的解析解答。与已有相关问题的解析解答进行对比，验证了此解的正确性，并给出算例，分析了入射频率对柱面上的应力集中因子的影响。

| Abstract: | On the basis of Biot dynamic theory,the dynamic response of cylindrical cavities to incident SV waves is investigated.An analytic solution is derived for the cavities embedded within a fluid-saturated porous media half space by using Fourier-Bessel series expansion technique in this paper.The solutions are proofed by comparison with the existing related solutions.Numerical results are given and the effect of the dimensionless frequency of the incident SV wave on the dynamical stress concentration factor on ... |
