Based on the in-situ data of soil layers along Suzhou rail transit lines and some other engineering sites, this paper uses the two different sand liquefaction judgement methods specified in the China Code for Seismic Design of Buildings（Version 2016） and General Rules for Performance-based Seismic Design of Buildings（Rev. 2019） to carry out the comparative analysis of the liquefaction discrimination results of the engineering sites in the main urban areas of Suzhou. There are obvious differences in the results of liquefaction discrimination between the methods in the current codes of China and the general rules. The results of the normative method are more conservative in the discrimination of liquefaction. It clarifies the limitations and conservatism of the methods in the current codes of China and the advancement and adaptability of the General Rules. At the same time, ArcGIS software is used to draw the map of liquefaction area in some areas of Suzhou by Kriging interpolation method, and the non-liquefaction areas, slight liquefaction areas, medium liquefaction areas and severe liquefaction areas are all divided and compared, which provides references for evaluating liquefaction areas in engineering construction of Suzhou City.

The elastic sliding isolation bearings were fixed at the top of the middle columns, a two-dimensional finite element model for the static-dynamic coupling interaction of soil-underground structure was established, and the seismic response of underground subway station, such as the lateral deformation, stress responses and the seismic damage were analyzed. It showed that the elastic sliding bearings fixed on the top of columns could effectively mitigate the seismic damage of the middle columns and the middle plate and keep middle columns completely under compress condition during the earthquake. As a result, it could improve the overall seismic performance of the underground station structure due to the important role of middle columns in the seismic resistance of underground subway station. However, the elastic sliding bearings fixed on the top of columns could also weaken the anti-lateral rigidity of the underground station structure and the plane buckling rigidity of the plates, which significantly amplified the lateral deformation response of the underground station structure. Meanwhile, middle columns changed the dynamic deformation mode of the underground station structure, which obviously aggravated the seismic damages of the top and bottom plates close to the side wall of the underground station structure.
