Seismic Acceleration Spectrum of Ground Surface under Urban Subway Tunnels with Circular Cross Sections in Soil Deposits Based on SSI

<div>Mean and <i>μ</i> + <i>σ</i> for log of the spectral acceleration for models in the presence (SF) and absence (FF) of a tunnel at a distance of 15.17 m from the center of the tunnel projection onto the ground surface.</div>
