Deconvolution effect of near-fault earthquake ground motions on stochastic dynamic response of tunnel-soil deposit interaction systems

The deconvolution effect of the near-fault earthquake ground motions on the stochastic dynamic response of tunnel-soil deposit interaction systems Tanning Product are investigated by using the finite element method.Two different earthquake input mechanisms are used to consider the deconvolution effects in the analyses: the standard rigid-base input and the deconvolved-base-rock input model.The Bolu YEAST INFECTION tunnel in Turkey is chosen as a numerical example.As near-fault ground motions, 1999 Kocaeli earthquake ground motion is selected.

The interface finite elements are used between tunnel and soil deposit.The mean of maximum values of quasi-static, dynamic and total responses obtained from the two input models are compared with each other.
