## 1 Introduction
The LIQ-UEFACT project within the EU Horizon 2020 program just ending in October 2019 carried out a total of thirty-seven dynamic centrifuge tests including benchmark tests of saturated sand under free field conditions [31; 32]. Extensive research other than theses remarkable collaborative projects has been conducted to evaluate soil liquefaction through centrifuge tests and could not be listed exhaustively. On the other hand, based on the well-documented experimental data, the state-of-the-art constitutive and numerical modelling methods for soil liquefaction are validated and further improved by researchers. [PERSON] et al. [33] assessed the seismic response of a layered liquefiable soil profile with granular columns through both numerical and centrifuge modeling. The numerical simulations are performed with PDMY and Manzari-Dafalias model in Opensees. Comparisons of numerical simulations with experimental results indicate a good prediction ability for both models on the peak value and generation of excess pore pressures during shaking. Similarly, implementing FE analyses with PDMY model in Opensees, [PERSON] et al. [34] simulated the centrifuge test of the saturated silty site improved with granular columns and analyzed the dynamic characteristics such as ground acceleration and pore pressure. The results suggested a good agreement between the simulations with the experimental measurement. As one of the main work packages in LEAP-2017, eleven sets of Type-B predictions were implemented with PM4 Sand model, PDMY, Hypoplastic model, Tsinghua constitutive model, etc. [PERSON] et al. [28] presents the comparisons of the Type-B simulations with the results of the centrifuge test and concluded that although similar trends can be achieved by a number of numerical simulations, predicting all the key quantities remains a challenge. Ports are of high political and economic value, and their destructive consequences can be unbearable. The Tibar Bay Port Project (TBPP), located on the Circum-Pacific Belt, has a high seismic fortification intensity according to Chinese standards. The design seismic acceleration (475-year return period) of the wharf area reaches up to 0.53 g on the basis of the seismic hazard assessment report for TBPP. The site is mainly underlain by a mixed layer of sand and gravel with a maximum thickness of 40 m, which is very loose to loose, and a locally medium dense state. A high proportion of fine sands can be found in local areas, and the average percentage of fines content smaller than 0.075 mm is 19% as shown in Figure 1. The layer has an average natural density of 1.65 g/cm\({}^{3}\). The SPT value ranges from 0 to 18, with a mean value being 7, and the design relative density is 50%. The design permeability is 6.4 \(\times\) 10\({}^{-2}\) cm/s. In order to scientifically evaluate the liquefaction potential of the calcareous sand site, centrifuge tests are carried out in the centrifuge shaking table system of Tongji University. Saturated calcareous sand models are tested with different relative densities under excitations of sets of input ground motions with different peak accelerations. The development characteristics of excess pore pressure at different depths during the earthquake are investigated, and the factors affecting excess pore pressure are analyzed in the tests. Moreover, based on the [PERSON]'s dynamic consolidation theory, seismic response analyses of the calcareous sand site are conducted on OpenSees. The dynamic pore pressure responses are simulated and compared with that in centrifuge models. The seismic liquefaction potential of calcareous sand sites is comprehensively evaluated.
