A numerical parametric study was conducted on diverse soil-rectangular tunnel systems,
aiming to shed light on critical response characteristics of rectangular tunnels subjected to
transversal ground shaking. Salient parameters that affect the dynamic response, such as:(i)
the soil-tunnel relative stiffness and interface properties,(ii) the shape, dimensions and burial
depth of the tunnel section,(iii) the soil deposit characteristics, and (iv) the input motion
characteristics, were accounted for in this study. This paper summarizes the key findings of …
