Abstract
Due to the fact that there is less domestic guidance for the design of underground structure response displacement method in the urban rail transit construction code for seismic design, this paper focuses on the differences in the formulas to calculate the displacement and shear force of the stratum defined in the specifications of China and Japan. The comparison of the calculations based on a metro station shows that Japanese specification addresses more on safety for the calculation of station embedded in soft soil layer, while the Chinese specification focuses more on safety for the calculation of station embedded in hard soil layer. It is recommended that for seismic design, where the soil shear wave velocity is greater than 300 m/s, safety reserves should not be excessively maintained and some reduction of seismic motion may be considered in combination with safety assessment parameters.关键词
