Abstract：The response deformation method for seismic analysis of underground structures is introduced. Based on the physical concept and basic principle of the response deformation method，an integral response deformation method is proposed to reduce the error source of the original method. The integral response deformation method takes the soil-structure model to realize the interaction between soil and structure. In order to verify the efficiency of the improved method，on the one hand，the improved method is proved to be consistent with the response deformation method in the physical concept；on the other hand，the improved method is compared with the dynamic analysis method by numerical calculation. It can be found from the numerical results that，compared to the response deformation method，the integral response deformation method requires less computational complexity and achieves more accurate result. The integral response deformation method is proved to be a highly practical pseudo-static method.
