Wave-induced load is one of the most important aspects in the design of coastal engineering. It is well known that long period waves are very common along the coast of the Atlantic and India ocean, which is rather different from wind waves. Many coastal projects were designed by China Design Code and American Coastal Engineering Manual (CEM). Physical model test was carried out in this paper to study wave loading of crest wall under impulsive action by long-period wave. The result of test was compared with China Design Code and CEM. And then a verification test was also adopted to prove that there was obvious difference between them. It was indicated that China code and CEM had very close results but much smaller than that of model test, with ratio of 1:5. The long-period wave load on crest wall was much more than results by empirical formula. The isolated crest wall and rear unsupported was also taken up with wave action and it was destroyed easily. So impulsive action by long-period wave on crest wall should be paid more attention in project design. The scope of empirical formula is limited and physical model test is indispensable for the reliability of structure.
