Combining with the current Seismic ground motion parameters zonation map of China and the seismic design codes for water transport engineering and related industries,the influence of the change of seismic ground motion parameters zonation map on the seismic design codes of various industries is discussed.The significance of horizontal earthquake coefficient and dynamic magnification factor in seismic design of water transport engineering is expounded.According to the new version of the seismic ground motion parameters zonation map,suggestions for the values are put forward.The urgency of revising code for seismic design of water transport engineering is pointed out.It can provide reference for correct understanding of seismic design code standard of water transport engineering structure and reasonable selection of seismic ground motion parameter.It is of positive significance to promote the systematic work between upper and lower levels of the seismic design standards.
