达尔布特断裂地震动场估计的有限断层震源模型
|
摘要
借助混合滑动模型,考虑震源参数不确定性,为新疆达尔布特断裂设定6.0级和6.5级地震建立了有限断层震源模型。全局震源参数通过全球参数定标律结合区域地质几何特征确定;以全局震源参数为依据,借助半经验定标律确定局部震源参数。进一步利用截断正态分布,表达震源参数的离散性,生成30组各异的震源参数值组合,与k平方模型结合,形成多组有限断层震源模型。选取达尔布特断裂周边150 km范围内不同距离代表性工程场点,借助有限断层随机地震动合成方法以及反应谱残差评价准则,选定达尔布特断裂设定6.0级和6.5级地震的"平均"震源模型,可为达尔布特断裂地震动场估计和地震危险性评估服务。
With the hybrid slide model and the random seismic parameters of the earthquake, the finite fault source model was established for the scenario earthquake 6.0 and 6.5 of Daerbute fault in Xinjiang province. Global seismic source parameters are determined by global parameter calibration law combined with regional geological geometric characteristics; Based on the global source parameters, the local source parameters are determined by the semi-empirical calibration law. Furthermore, 30 sets of different value combinations of seismic source parameters are generated by truncation normal distribution to express the discreteness of seismic source parameters, combined with k square model, multiple finite fault source models are formed. Representative engineering sites at different distances within 150 km around Daerbute fault were selected by means of the method of random seismic synthesis of finite faults and the criterion of residual evaluation of reaction spectrum, the "average" seismic source model of scenario earthquake 6.0 and 6.5 was selected to service for seismic field estimation and seismic risk assessment of Daerbute fault.
