A STUDY ON THE SITE-SPECIFIC EARTHQUAKE GROUND MOTION AND THE SEISMIC PERFORMANCE OF SHIELD TUNNEL IN THE LONGITUDINAL DIRECTION

Abstract

This paper is to study the site-specific earthquake ground motion for the seismic design of shield tunnel. The site-specific earthquake ground motion is studied based on the fault model. Then, the seismic performance of shield tunnel in the longitudinal direction is estimated for the peak ground strain. The peak ground strain is approximated to sinusoidal wave and compared with the current manual's wave. As a result, sinusoidal wave length of the fault model is longer than the current manual's.
