Development Characteristics and Disaster Mechanism of Debris Flow in Daofu Section of Xianshuihe Fault Zone
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
