摘要
磐石市富太镇地区泥石流灾害较为发育,给当地人民的生命财产、交通安全构成了一定的威胁。为了为合理制定泥石流防治方案和进行泥石流防治工程设计提供依据,文章采用模糊数学综合评判法和泥石流最大危险范围预测模型分别对富太地区的21条泥石流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:本区泥石流危险程度基本都属于轻微级,而且它们的最大危险范围也较小,符合富太地区的实际情况。
Lives and property of local people and local traffic safety have been threatened by the developed debris flow hazards in the Futai Town of the Panshi City. In order to provide scientific base for making out control schemes and designing prevention projects of debris flow, risk evaluation and maximal hazardous dimension forecast of 21 debris flows in Futai were carried out with a fuzzy mathematic comprehensive evaluation method and a maximal hazardous dimension forecast model. The results show that each debris flow in this area is slightly risk and its maximal hazardous dimension is comparatively small, which are coincident with the status of the study area.
