北京山区泥石流预警阈值初步研究
Preliminary Study on Early Warning Threshold of Debris Flow in Beijing Mountainous Area
摘要
Abstract
The warning threshold is the critical reference index to monitor debris flow. According to the characters of debris lfow in Beijing area and theoretic research in the ifeld, two aspects contents are introduced in the article: 1) based on hazard tendency, provenance and the number of victims, debris flow ditches are divided into three levels. The authors propose rain thresholds for different ditch level, antecedent rainfall and hazard probability. This method provides the convenience for medium and short-term warning; 2)The rainfall value, water-content of soil , infrasonic wave information as well as the mud level are chosen as the four indexes of early warning of debris lfow. And the threshold values are studied in the paper. Finally, the system of warning threshold of debris lfow is established ,which can offer technical support for early warning of debris lfow.关键词
