摘要 基于唐山地区大量的钻孔和波速测量等资料以及京津唐地区地壳结构模型,建立了唐山地区三维地下速度结构模型。利用宽频带地震动模拟方法模拟了1976年唐山大地震的近场地震动,给出了极震区加速度时程和反应谱,并与烈度分布以及其他研究结果进行比对,本研究可为唐山市防震减灾提供参考。 A 3-D velocity model of Tangshan area is constructed in this paper based on the extensive drilling data in Tangshan area.The near-field broad-band strong motion of the 1976 great Tangshan earthquake is numerically simulated,and the results are contrasted with the seismic intensity map and other researcher's results.The results of this paper can provide some reference for earthquake prevention and disaster reduction of Tangshan City.
