    • Abstract
  • Adopting field investigation and indoor model tests, the characteristics of debris flow in Baitan Gully are studied. Combined with the particularity of terrain, geological conditions and building layout, the drainage route of debris flow is compared. The optimal drainage route is obtained. In addition, the effect of control measures of debris flow in Baitan Gully is evaluated. The results show that the guide wall, block dam and solid bed dam can effectively protect the original channel, and they can also prevent solid substances from being involved in debris flow activity. Beyond that, the silting field can also play the role of silting. Finally, only a small amount of solid substances and the flood are discharged to the Jinsha River through the drainage cannal, and the effect of prevention is achieved. As a complete system, the guide wall, block dam, silting field and solid bed dam can have a good control effect. So such a control system should be widely adopted in the design of control measures for debris flow.
