Review on research of ground motion site adjustment coefficient

This paper reviews and summarizes the main research results on the adjustment coefficients of ground motion field at home and abroad over the past 20 years, focusing on the effective means of considering the influence of filed conditions on ground motion parameters through strong ground motion observation and numerical theory methods. It summarizes the applicability along with the pros and cons of various methods, conducts a comparative analysis of the main results at home and abroad by combining relevant codes and provisions, and concludes that the coefficients of soft soil field in China are smaller than the international level. What’s more, the reasons for this difference are further analyzed. Finally, based on the current development trend of international seismic zoning work and the new technical requirements of the relevant codes in various industries, it puts forward prospects for the research work of the new generation of zoning maps.
