| 英文摘要 | The superelevation phenomenon is common in the movement of debris flows around curves. This paper presents a new method to calculate the superelevation of debris flow when it encounters obstacles in the flow process. The calculation method is based on the Bingham Model for debris flow determination. In this paper, physically significant internal and external roughness coefficients are determined by analysing the internal characteristics and external channel boundary conditions of viscous debris flows in Xiedi gully, China. According to the situation of debris flow passing through the bend, when the debris flow moves to the sidewall of the gully with velocity, the movement state is divided into two parts: radial and normal. One part of the mud rock fluid continues to move in the tangential direction and generates superelevation, and the other part moves in the radial direction and generates upward climbing along the sidewall. Thus, the formula for calculating the superelevation of debris flow bend is derived. Based on the debris flow physical and dynamic parameters, such as density and weight of the debris flow, cohesion, internal friction angle, yield stress and dynamic viscosity of liquid-phase slurry, the reliability of the formula is verified, which provides a theoretical basis for future studies of debris flow disaster prevention and control in similar areas. |
