Abstract
In this paper, a two-dimensional V-shaped Canyon-Bridge model with three depth-to-half-width ratios is constructed and the theoretical solution of the physical variables of the bridge deck is derived. The wave field of V-shaped canyon under the incident anti-plane shear waves (SH waves) is derived in frequency domain based on the classical elastic wave analytic theory. The time domain wave field of canyon is obtained according to Fourier transform. The bridge displacement input is given according to the wave time-histories. The displacement responses of the bridge deck are derived from the multi-point input of the bridge, and the velocity and acceleration responses are obtained through derivation. The results show that both the amplification effect and the shielding effect of canyon on waves will affect the bridge input and response and are greatly affected by the depth-to-half-width ratio of the canyon. The dangerous location of V-shaped canyon bridges is speculated based on the theoretical results and the actual situation, which provides guidance for the seismic protection of canyon bridges.
