| 摘 要： | 利用高精度交错网格有效差分技术,以及参数平均算子实现非水平地表条件下瑞雷波全波场模拟.针对地裂缝的特殊地形条件进行瑞雷波的传播模拟,从炮记录和频散曲线两个方面讨论其传播特征.实验表明：不均匀浅地表地形条件会对能量的分配以及波形的转换产生影响,在勘探时要尽量对其加以避让.

| Abstract: | Through high-order staggered-grid finite-difference operators and parameter-averaging scheme, propagation of Rayleigh waves at ground fissure was simulated and the characteristics discussed from two aspects of shot-records and dispersion curves. It is showed that uneven surface topography will affect the distribution of wave energy and waveform conversion, which should be avoided in the prospecting. |
