Abstract:An underground structures’ simplified aseismic analysis method named the integral forced response dis-placement method was proposed to directly take soil deformation as equivalent earthquake loading.The fundamental idea and the specific implementation steps were introduced.Since the equivalent earthquake loading was obtained through free-field seismic response analysis, its accuracy was influenced by soil condition and the structure itself, so the accuracy of the integral forced response displacement method was also affected.The applicability of this method was analyzed through changing underground structure type, its burial depth and base soil stiffness.The results obtained with this method in vari-ous cases were compared with those using the dynamic time history analysis.It was shown that the integral forced response displacement method has a good applicability and a satisfactory accuracy in most cases, and the method is suitable for aseismic analysis and design of underground structures in soft soil.Considering the soil-structure relative stiffness in aseis-mic analysis of underground structures, the structure shear deformation correction coefficient R was proposed to modify this method.The checking calculations showed that the modified integral forced response displacement method has smaller er-rors and a wider applicability.
