| 摘 要： | 设定地震常用于震害预测、地震小区划和重大工程选址，烈度衰减模型反映了地震引起的地面震动及其影响的强弱程度分布。设定地震包括确定性和非确定性设定两种方法，确定性方法基于构造或历史地震，非确定性方法是基于概率危险性方法，用于估计区域或城市未来可能遭遇的地震危险。缺失等震线或震害记载不详的历史地震和概率设定地震都不能确切地反映地震破坏影响，借助于烈度衰减关系模型和GIS，可直观地判别其影响分布情况，便于设定地震的取舍。

| Abstract: | Scenario earthquakes are commonly used in earthquake disaster prediction, seismic micro-zoning and critical engineering siting. Rating of disaster caused by earthquake is reflected in intensity attenuation relationship model. There are two methods in determining the scenario earthquake, i.e. certain and uncertain methods. The first method is based on crustal structures or historical earthquakes, whereas the second one is based on probabilistic seismic hazard analysis method, and is used for estimating seismic hazard in one region or city in the future. When the isoseismal line or seismic hazard record is missing, both historical earthquake and probabilistic scenario earthquake can not reflect earthquake disaster accurately. If we use the intensity attenuation model and GIS together, the distribution of earthquake disaster influence can be directly drawn and scenario earthquakes can be easily selected. |
