岫岩县泥石流趋势预测预报

Prediction and Forecast of Debris Flow in Xiuyan Country

鞍山市岫岩县属于暴雨多发地区,受大暴雨侵袭时易爆发泥石流。为实现对泥石流趋势的有效预测预报,选择"降雨因子"FR和"地质因子"FG作为预报指标,通过两者的积来量化泥石流易滑程度,划分泥石流灾害趋势预报的等级标准。

It is heavy rain-prone areas in Xiuyan country Anshan city,and it is easy to break out debris flow when attacked by heavy rain.In order to predict and forecast the occurrence trend of debris flow effectively,"rain factor"FR and"geologic factors"FR were chosen as prediction indictors,and the identification of the slippage degree of debris flow could be quantified by the product of rainfall factor and geological factor,and then the grading criterion for debris flow disaster trend prediction was divided.
