利用瑞利面波特性计算动力响应的进一步探讨

Discussion on Calculating Dynamic Resoponse of Soils Using Rayleigh Wave Characteristics

本文根据地基中瑞利面波的能流分布规律，提出了利用面波的第一模态波模拟水平向传播波，而竖向传播波则采用半无限单元模拟。通过算例验证了本文方法的可靠性和精确性，并与传统的传递边界法进行了比较，最后讨论了衰减系数中对计算结果的灵敏性。

Based on the energy distribution law of Rayleigh surface wave in soils, the borizontal propagation wave in soils is simulated using the first model wave of surface wave and the vertical propagation wave is simulated using semi-infinite elements in this paper. The availability and accuracy of the presented method in this paper is verified by numerical examples. The result calculated by the presented method is compared with that calculated by transmitting boundary method. The sensitivity of coefficient is discussed.
