【摘要】：为了更好地预测地震滑坡的危险性,根据信息融合,提出一种基于证据理论和熵权灰色关联法的地震滑坡危险性预测模型,即以证据理论为模型基础,以滑坡危险等级为识别框架,根据地震滑坡发生所需要的条件,选取岩石风化系数、地震烈度、断裂带密度、河网密度、相对高度、山体坡度这6项指标作为证据体,并采用熵权灰色关联法确定各证据体的确定信度。通过分析并且采用国内若干组滑坡实例对模型进行验证。研究结果表明:该方法具有较高的预测精度,可靠合理,能满足抗震防灾规划要求。
[Abstract]:In order to better predict the risk of earthquake landslide, according to the fusion of information, a prediction model of seismic landslide risk based on evidence theory and entropy weight grey correlation method is proposed, which is based on evidence theory. Taking the dangerous grade of landslide as the identification frame, according to the conditions needed for the occurrence of earthquake landslide, six indexes of rock weathering coefficient, seismic intensity, density of fault zone, density of river network, relative height and slope of mountain body are selected as evidence body. And the entropy weight grey correlation method is used to determine the reliability of each body of evidence. The model is verified by analyzing and using several sets of landslide examples in China. The results show that the method has high prediction accuracy, reliability and rationality, and can meet the requirements of seismic disaster prevention planning.
