Abstract
This paper presents a numerical simulation method to examine the damage mechanism of bridge superstructure washed away by tsunami flow. To demonstrate a capability of the proposed method, the proposed method is applied to simulate the slab bridge behavior washed away by the tsunami flow of the 2011 off the Pacific Coast of Tohoku Earthquake (M9.0) in Japan, and the mechanism of the slab bridge damage is discussed. And also some hydraulic experimental results are compared with the numerical simulation results to confirm the validity of the proposed numerical simulation method.
