Paper Title:
Study on the Damage Mechanism of Bridge Pier and Foundation by Turbulent Debris Flow
  Abstract

The debris flow is the uppermost water-destroyed type of highway, which caused large direct economic loss annually in china, especially in mountainous area highway small bridges and culvert damaged seriously. This paper started from the theory of debris flow two-phase flow, it is divide turbulent debris flow into liquid and solid, and with the turbulent debris flow wash against bridge pier increased, the erode depth overpass the burial depth of foundation, base bearing capacity reduced gradually and then result bridge pier instability; in addition for the strong force of impact of debris flow resulted in resistance to capsizing weaken. The damage of bridge and culvert’ foundation mainly duo to the erosion, which lead to the erode depth overpass the burial depth of foundation, furthermore, debris flow force of impact greater then structure resistance and result the structure instability and damaged.
