分析了淤地坝溃坝的暴雨洪水特征及其影响因素,从地理信息角度对这些因素进行信息解析形成模型参数,以之为基础构建了淤地坝溃坝预报预警地理信息模型。针对某淤地坝,按照不同的暴雨洪水和库容状态进行了模拟分析,确定了对应状态下坝体的安全状态,形成预报预警结论,表明了淤地坝溃坝预报预警地理信息模型应用的可行性。
This paper analyzes the characteristics and influencing factors of storm flood and flood dam and the influencing factors, constructs the model parameters by analyzing the information from the perspective of geographic information, and constructs the model of dam warning and warning information. Aiming at some silt dam, the simulation analysis is made according to the different storm floods and the storage capacity, and the safety status of the dam body is determined and the forecasting warning conclusion is formed. It shows that the application of the siltation dam precaution and warning geographic information model is feasible Sex.
