Abstract

Abstract

On August 23, 2022, a mass debris flow demage occured in Qunying Village, Leyue Town, Dechang County, resulting in serious blockage of the village road from Qunying Village to Taiping Village, and ruination of large areas of arable cash crops on both sides of the road. In order to reveal the development law of the mass debris flow, the formation mechanism and dynamic characteristics of the debris flow in Wangjiapo were comprehensively studied by combining field investigation and remote sensing images. The research results show that in the short duration of heavy rainfall, the quickly formed surface runoff after the infiltration of water into the slope gathered in the gully, then the water along cut andside eroded the gully bank and slope and formed a large number of loose solid material, resulting debris flow damage after the rising large scale debris flow ran out of the gully mouth. The dynamic reserves of loose accumulation in the debris flow gully are 1.21×10⁴m³, which can be divided into three provenances: gully provenances, landslide provenances and erosion provenances, among which gully provenances account for the largest proportion. Finally, the flow and impact force of debris flow under the condition of different rainstorm frequency are calculated to provide reliable data and corresponding prevention and control measures for debris flow demage prevention inWangjiapo Gully.
