Abstract: This paper attempts to discuss several issues in China’s earthquake engineering researches and disaster reduction undertakings based on a philosophical and scientific points of view. The paper points out that the seismic intensity by macroscopic investigation does not have the exact connotation and extension of scientific concepts, it is impossible to verify the results risk analysis, the adoption of seismic fortification standards fundamentally depends on the development level of social economy and technology, the research of fault avoidance has not yet reached the stage of engineering application, the exact results of numerical simulation of structural seismic response cannot be pursued. Finally, some of suggestions and prospects for seismic engineering researches are proposed.
