%X Underground tunneling is one of the alternative solutions to diminish
traffic congestion in large cities. One of the most important effects of
tunneling is the displacement of the ground surface, the settlement around the
tunnel, and the variation in earthquake acceleration. The performance and
behavior of underground structures have been studied by several researchers,
but the impact of tunnel excavation on earthquake records and its effects on
structures above the ground level ha</span></span><span style=\"font-size:12px;font-family:Verdana;\"><span style=\"font-size:12px;font-family:Verdana;\"><span style=\"font-family:Verdana;font-size:12px;\">ve</span></span></span><span style=\"font-size:12px;font-family:Verdana;\"><span style=\"font-size:12px;font-family:Verdana;\"><span style=\"font-family:Verdana;font-size:12px;\"> received less attention. This research emphasizes changes of earthquake
acceleration at the ground level, structural response and Fourier spectrum by
excavating a horseshoe tunnel. Results show that digging a horseshoe tunnel
will change the characteristics of the earthquake record at ground level.
