Abstract: According to the type of slope collapse, erosion type, distribution regularity of landslide debris flow types and characteristics of slope debris flow on slope, a simplified calculate on method for the groove bottom of the highway drainage structure on the hillside is proposed. Compared to the traditional method it is more simple, providing technical reference for the management of debris flow. Keywords: Highway; Debris flow; Groove bottom
