In this study, a comprehensive parametric analysis was performed on non-uniform excitation of V-shaped topography using the boundary element method in time domain. For this purpose, wave scattering analysis was carried out on a topography subjected to the SV-wave for different predominant frequencies and shape ratios. Based on the numerical results, new coherence and time delay functions are proposed to generate non-uniform ground motion for topographic irregularities. The efficiency and accuracy of the proposed functions for real engineering problems are indicated by comparison with observations reported in previous literature.

引入有效的相干函数，使用时域边界元方法在地形站点上生成不均匀的地面运动

在这项研究中，使用时域边界元方法对V形地形的非均匀激励进行了全面的参数分析。为此，针对不同的主要频率和形状比，对经受SV波的地形进行了波散射分析。基于数值结果，提出了新的相干性和时延函数，以生成地形不规则性的不均匀地面运动。通过与先前文献中报道的观察结果进行比较，可以表明针对实际工程问题的拟议功能的效率和准确性。
