【摘要】 本文建立了非均匀的唐山主震断层模型,利用广义反射-透射系数矩阵和离散波数方法,考虑局部场地效应,给出了唐山、迁安、宁河、玉田、天津、北京等地地震动时间过程的数值模拟结果。文章通过比较分析并结合唐山地震震害特点论述了数值模拟结果的合理性。更多还原

【Abstract】 An inhomogeneous fault model of the Tangshan earthquake is developed in this paper. A series of synthetic seismograms of the event are calculated by using the RTDW (Generalized Reflection -Transmission Coefficient Matrix in Discrete Wavenumber) method in consideration of the local site conditions. Moreover,by comparing with real seismic damage during the earthquake and other numerical results,the rationality of the results obtained in the paper is discussed.更多还原
