Abstract A utility tunnel system consists of pipes and ancillary facilities. In this paper, a
finite element model of a concrete utility tunnel with pipes inside is established. Several
tunnel segments were built to simulate a real utility tunnel, while the pipe was fixed by
springs on the brackets in the utility tunnel. Using the discrete soil spring element to
simulate the soil-structure interaction, actual earthquake records were adopted as excitation
to analyze the seismic responses of pipes in a utility tunnel. Moreover, the influences of
different parameters, including soil type, earthquake records, and field apparent wave
velocity on the seismic… More >
