针对土石坝溃决损失评估涉及众多地理空间对象且影响因素多而复杂的特点,基于GIS空间信息格网模型与支持向量机建立了土石坝溃决损失评估模型.利用GIS空间信息格网模型组织和管理大量空间信息数据,应用支持向量机评估溃坝生命损失率.以评估模型为基础,构建了土石坝溃决损失评估系统.实例应用研究表明,利用该系统可实现土石坝溃决损失快速评估,精度较高,效果较好.可为土石坝风险管理以及防灾减灾、救援决策提供参考.

The evaluation of loss caused by earth-rock dam break involves in many geographical spatial objects, and its influencing factors are manifold and complex. Therefore, the evaluation model of loss caused by earth-rock dam break the model was established based on GIS spatial information grid combined with support vector machine. The GIS spatial information grid model was used to organize and manage the number of spatial information data. Support vector machine was used to evaluate loss-of-life rate caused by dam break. The evaluation system of loss caused by earth dam break is established based on evaluation model. Application showed that the method has high accuracy and good effect in rapid evaluation of loss caused by earth-rock dam break, which can provide reference for the dam risk management, disaster prevention and mitigation, and aid decisien-making.
