| 摘 要： | 基于可拓学的物元模型和聚类分析原理，提出了地质灾害危险性评价的可拓聚类预测方法。本文根据地质灾害危险性的9个影响因子，构建了经典域物元和节域物元，应用物元理论和可拓集中的关联函数建立预测模型，通过聚类分析得到地质灾害危险性的预测结果。并将可拓聚类预测方法用于对云南昭通地区滑坡、泥石流危险性评价之中，实例研究表明了可拓聚类预测方法用于地质灾害危险性评价的有效可行性。

| Abstract: | Based on the matter-element model and the classified analysis method,an extension classification prediction method for risk assessment on geological hazards is proposed. In the method, 9 influence factors on geological hazards are adopted to establish the classical and extensional mater elements,and the dependent function of material element and extension set is applied to establish prediction model for risk assessment on geological hazards. The predicting results of the stability of rock-mass slopes are obtained by applying the classified analysis. Through risk assessment on landslide and debris flow in Zhaotong county of Yunnan Province,the results show that extension classified prediction is available in risk assessment on geological hazards. |
