摘要
洛门镇响河沟泥石流给当地人民生命财产、交通安全构成了一定威胁。为了给合理制定泥石流防治方案和进行泥石流工程设计提供依据,文章采用泥石流最大危险范围预测模型进行了危险性评价和最大危险范围的预测。评价和预测结果表明:响河沟泥石流危险程度基本属于显著危险,最大危险范围较大,符合实际情况,对泥石流沟道的治理有一定的指导意义。
Local people＇ s lives and property and traffic safety have been threatened by the developed debris flow hazards in the Xianghegou River of Luomen Town. In order to provide a scientific base for making out control schemes and designing prevention projects of debris flow, the risk evaluation and maximal hazardous dimension forecast of debris flow in the Xianghegou River was carried out with a maximal hazardous dimension forecast model. The results show that the debris flow in Xianghegou River is obviously risky and its maximal hazardous dimension is comparatively small, which are coincident with the status of the study area.
