The contrast calculation and statistic analysis in 18 cases of gravity wharf on the basis of current codes and the under-revision codes to anti-sliding and anti-overturn stability are carried out. The result reveals that the anti-sliding and anti-overturn stability calculated by the under-revision Design Code for Wharf Structure,which introduces the comprehensive resistance coefficient γR and adjusting structure coefficient γd, is almost the same as that calculated by the present code. Therefore, the revisions are feasible and reliable.
