摘要
为查明热水河沟泥石流对沿江高速和流域居民的影响,通过现场调查、数据统计和定量预测等方法,分析了泥石流形成条件,论述了其主要特征,并对泥石流易发程度开展数量化综合评判分级,预测了它的发展趋势。研究结果表明,热水河流域地形陡峻,支沟发育,物源丰富,降雨集中,总体上有利于泥石流灾害的孕育;该泥石流属暴雨沟谷型泥石流,易发程度为易发,目前处于发展期(壮年期),未来再次暴发风险较高,需采取综合措施进行防治。
In order to investigate the influence of debris flow in the Reshui river gully on the Yanjiang expressway and residents in the basin,the formation conditions of debris flow were analyzed by means of field investigation,data statistics and quantitative prediction,and their main characteristics were discussed.The quantitative comprehensive evaluation and classification of debris flow susceptibility were carried out,and its development trend was predicted.The results show that the terrain of Reshui river basin is steep,the branch gully is developed,the source is rich,and the rainfall is concentrated,which is generally conducive to the breeding of debris flow disasters.The debris flow is a rainstorm gully debris flow,which is prone to occur.It is currently in the development period(mature period),and the risk of recurrence in the future is high,so comprehensive measures should be taken to prevent and control it.
