Abstract

The main content of this paper is the preliminary numerical simulations of a 1g shaking table test on shaft-tunnel junction in liquefiable soil. In addition to the soilstructure models, a free-field model is also considered. They are all computed using the OpenSees platform, and the PM4Sand constitutive model is used to characterize the properties of liquefiable Fujian sand. The presented data include the excess pore pressure and the vertical displacements of the structures. It has been demonstrated that the difference between the uplifts of the shaft and the tunnel is quite significant, posing a potential threat to the seismic safety of this type of underground structures. These preliminary simulations make a reasonable prediction for the future shaking table test, thus contributing to the design, the execution, and the interpretation of the test.
