某正倾滑断层引起的近断层强地面运动的有限元数值模拟
Models and methods for simulating near-fault ground motion field of a city by explicit finite element method
【摘要】 本文使用与文献[1]相同的数值模拟方法,预测了某城市设定矩震级为MW=6.75的活断层产生的近断层强地面运动。主要定性计算结果是:正倾滑断层(倾角δ=75°)产生的近断层强地面运动也不同程度地存在上盘效应、F ling Step效应、速度大脉冲效应和竖向效应。表明本文采用的震源模型和计算方法可以实际应用于预测城市近断层强地面运动影响场。
【Abstract】 In this paper,the models and methods for simulating the near-fault ground motion field of a city by explicit finite element method were illuminated and presented by using the data from the earthquake fault exploration,and the preparation for forecasting the near-fault ground motion field of the city was accomplished.
