Experimental modeling of adjacent parallel shield tunnels subjected to train-induced vibration loads

Abstract: Previous studies have performed numerical simulations of adjacent parallel shield tunnels under train-induced vibration loads. However, few experimental studies have been performed for the interaction mechanisms. In this study, experimental modeling is conduced to explore the interaction of adjacent parallel shield tunnels subjected to different train-induced vibration loads. A new Hilbert-Huang transform (HHT) is applied to obtain the instantaneous responses of tunnels. The results show that the acceleration … Show more

“…The surrounding soil, the lining structures and train tracks of existing tunnels which are crossed or overlapped will be deformed or damaged by the influence of the construction of new tunnels, and the safety of subway traffic will be endangering (Luo et al, 2014;Bo et al, 2014;Li et al, 2014). The existing tunnels, especially the operating subway will generate large dynamic stresses in the foundation under the cyclic train loads, which will adversely affect both the operating tunnel itself and the excavation of the tunnel under construction (Zhang et al, 2021;Huang et al, 2021;Gharehdash et al, 2015).…”
