摘要
该文选取道孚县城鲜水镇降不沟为例,对其发育特征及成灾机理进行研究,认为:鲜水河断裂带长期活动对泥石流的岸坡稳定性有很大影响;道孚县区域多暴雨和连绵雨,暴雨则是该地区泥石流发灾的决定性因素;泥石流的成灾模式主要为"侵蚀-坍塌-溃决".建议后期在泥石流的防治中,应结合流域内物源、沟道条件及城镇发展规划进行综合防治,并辅以相应的监测措施.
Abstract
This paper takes Jiangbugou,Xianshui Town,Daofu County as an example to study its development characteristics and disaster mechanism.It is concluded that the long-term activity of Xianshuihe fault zone has a great influence on the bank slope stability of debris flow.Heavy rain and continuous rain are common in Daofu County,and heavy rain is the decisive factor of debris flow disaster in this area.The main disaster mode of debris flow is"erosion-collapse-outburst".It is suggested that the prevention and control of debris flow should be combined with the provenance,channel condition and urban development planning,and supplemented by corresponding monitoring measures
