延怀盆地官厅水库大坝设定地震的地震动模拟
|
摘要
国内外相关研究表明,三维有限差分方法模拟地震动具有较高的准确性和可行性。结合相关理论与方法,利用延怀盆地地壳波速和密度模型,对延怀盆地官厅水库大坝设定地震的地震动进行了模拟。结果表明,模拟结果与用经验公式法所得结果吻合较好,得到的地震动速度时间序列、峰值速度等参数对大坝的结构抗震分析具有一定价值。
Researches at home and abroad show that the simulation of ground motion by 3-D finite-difference method can be accurate and feasible.Based on the related theories and methods,the paper uses the wave velocity and density model of the crust in the Yanqing-Huailai basin and makes the simulation of ground motion at the Guanting Reservoir Dam based on the scenario earthquake in the Yanqing-Huailai basin.The comparative analysis shows that the results of 3-D finite-difference simulation accord with those of empirical formula,the parameters such as the velocity-time series of ground motion,PGV and frequency might be referred for the analysis of seismic protection design of the dam's structure.
