Influence of approach shape of debris flow on impact load subjected to open Sabo dam under an overturning experiment of open Sabo dam

Recently high intensity rainfall disaster induces some structural failure of steel pipe open Sabo dam. To prevent such the dam, a new design concept is necessary at severe load exceeding present load. However, influence debris flow impact on dam not clear to make The study experimentally approaches vertical distribution shape and its time history based comparison with wedge approach or front boulder concentrated shape. moment action greater than that Mechanism making difference made by observation detail measurement
