摘要场地-城市相互作用(SCI效应)会显著改变场地地震波场分布及建筑反应，本文基于SCI效应理论计算研究方法的发展现状，发挥谱元法(SEM)可快速高效求解三维地震波场传播和多自由度(MDOF)模型计算量小且可同时模拟大量建筑的优势，同时，结合频率波数域(FK)方法，以等效地震荷载的方式施加地震波场，建立了FK-SE-MDOF耦合方法，实现了SE-MDOF耦合模型中多种波型(P、SV和SH)的斜入射输入，解决了当前三维SCI效应研究方法中未能同时考虑建筑非线性、频谱特性、地震波波型及入射角度影响的问题。文章首先对方法原理进行了介绍；然后，通过与振动台试验的对比，验证了方法的正确性；进而，采用该方法建立理想场地-城市建筑群相互作用耦合模型，主要探讨了入射角度和地震波波型对SCI效应的影响，得到了一些有益结论。该方法较为真实地反映SCI效应影响的同时，可反映建筑基础轮廓对地震波场的影响，适用于需考虑建筑轮廓信息的社区尺度SCI效应研究，可为城市规划、抗震设计、风险评估以及震后救援等工作提供定量指导。

Abstract：The site-city-interaction (SCI) effect will drastically modify the seismic wave field and the response of buildings. Based on the development status of SCI effect simulation approach, taking advantages of the spectral element method (SEM) and the multi-degree of freedom (MDOF) model, (i.e., SEM can efficiently simulate the three-dimensional seismic wave field propagation, and MDOF can simulate a large number of buildings at the same time), and combining with the frequency wavenumber domain (FK) method to input the seismic wave field by applying equivalent seismic loads, the FK-SE-MDOF approach is established. This approach can simulate the oblique incidence input of multiple wave-types (P, SV and SH) in the SE-MDOF coupling model, and solved the problem that the influence of nonlinear characteristics of buildings, spectrum characteristics, seismic wave-type and incidence angle cannot be considered simultaneously in previous three-dimensional SCI effect simulations. Firstly, the theory of the approach is introduced; Then, the correctness of the approach is verified by simulating an existing shaking table test; Furthermore, a series of ideal site-city-interaction models are established, and the influence of incident angle and wave-type on SCI effect is mainly discussed; Finally, some useful conclusions are obtained. The approach can realistically reflect the impact of SCI effects while reflecting the influence of building foundation contours on the seismic wave field. It is suitable for community-scale buildings where it is necessary to consider foundation contour information and can provide quantitative guidance for urban planning, seismic design, risk assessment and post-earthquake rescue.
