The increasing demand on creating underground space in seismic areas has dictated developing research to investigate the seismic response of basement walls. Previous studies indicated discrepancies in terms of the seismic earth pressure on basement walls due to differences in the assumptions related to the wall movement mechanism (yielding versus non-yielding). In this study, the seismic response of basement walls is investigated by developing a numerical model, based on the finite difference method, to simulate the interaction between the basement wall, backfill and foundation soils, and bedrock motion. The model also accounts for the effect of additional stresses from footings resting on the backfill soil. The study reveals an interdependence between the peak acceleration response and the peak seismic thrust and straining actions, which enabled developing empirical correlations to aid the seismic design. It is recommended to classify basement walls as partially-yielding walls from the perspective of their seismic response.

对在地震区域中创建地下空间的需求不断增加，因此需要开展研究来研究地下室墙的地震响应。先前的研究表明，由于与墙体移动机制（屈服与非屈服）相关的假设存在差异，地下室壁上的地震土压力存在差异。在这项研究中，通过建立基于有限差分法的数值模型来研究地下室墙的地震响应，以模拟地下室墙，回填土和基础土以及基岩运动之间的相互作用。该模型还考虑了来自回填土上立足的附加应力的影响。研究揭示了峰值加速度响应与峰值地震推力和应变作用之间的相互依存关系，这有助于开发经验相关性，以帮助抗震设计。从地下室的地震反应角度来看，建议将其分类为部分屈服墙。
