The effects of different control factors such as clay content, width height ratio, upstream inflow flow and initial water content on the collapse of gully blocking landslide material source are studied. Through the analysis of the collapse process of weir plug body, the collapse modes of weir plug body are classified. This paper summarizes the longitudinal evolution law of dam body contour under different failure modes, calculates the flow depth, flow velocity and erosion rate, analyzes the temporal and spatial evolution process of dam body under different failure modes, discusses the effects of different factors on the gravity of dam break debris flow and peak discharge, and establishes the mathematical model of dam break discharge amplification coefficient of weir plug dam, Two plugging points in the study area and one plugging point in Ginkgo Pinggou are selected for verification, but there are some limitations in practical application due to the complexity of weir plug dam failure.

A large number of engineering practices show that the total amount of slope material sources and dynamic reserves account for a large proportion of the total amount of material sources in the basin, which is an important source of debris flow after the earthquake. Through the indoor model test, this paper analyzes the sensitive factors of slope material source rainfall start-up, compares and analyzes the estimation results of slope material source dynamic reserves by engineering experience method and RUSLE model, and reveals the influence of slope re greening herb vegetation on slope material source seepage field through numerical simulation analysis on the basis of indoor model test.
