ABSTRACT

This paper aims to study the combined effects of incident wave angularity and geometrical characteristics on the seismic spectral response of curved valleys filled with alluvium. The parametric studies were carried out using a numerical tool, called HYBRID, which combines the Finite Element Method (FEM) and Boundary Element Method (BEM) to model the near field and far field, respectively. Some criteria were provided considering the coupled effects of wave incident angles, and topographical and geometrical characteristics on the seismic site response. This will help engineers in assessing the soil-structure interaction problems in alluvial valleys.

横波斜入射冲积河谷的地震响应

摘要

本文旨在研究入射波角度和几何特征对充填冲积层弯曲山谷地震光谱响应的综合影响。参数研究是使用称为 HYBRID 的数值工具进行的，该工具结合了有限元法 (FEM) 和边界元法 (BEM) 分别对近场和远场进行建模。考虑到波入射角的耦合效应，以及地形和几何特征对地震现场响应的影响，提供了一些标准。这将有助于工程师评估冲积河谷中的土壤-结构相互作用问题。
