邢台地区设定地震事件烈度影响

Scenario earthquake and intensity of the impact analysis in Xingtai area

通过邢台地区历史地震烈度资料分析,得到该地区烈度—频率灾害曲线及地震风险。以地震地质资料理论为基础,结合河北省城市活断层探测成果、地壳结构等资料,确定2个设定地震事件。采用复合震源模型,模拟合成强地面运动,并基于强地面运动模拟结果,分析邢台地区地震影响烈度,为今后该地区建筑物抗震设防、避难场所选址、震后救援以及地震保险风险评估提供参考依据。

In this paper, first of all, through the analysis of the historical earthquake intensity data in Xingtai, the disaster intensity in the region intensity-frequency curve and its earthquake risk is obtained. Then, based on the seismic geological theory, combined with urban active fault detection data and crustal structure data in Hebei Province, two scenario earthquakes are determined. Finally, by using the composite source model, the synthesis of strong ground motion is simulated. And based on the strong ground motion simulation result, the response intensity of Xingtai earthquake area is analyzed and some references are provided for later seismic fortification of buildings, location of the shelter, the earthquake relief, and the earthquake insurance risk assessment in Xingtai area.
