Abstract:As the foundation of the breakwater beacon,it is usually located at the part of jetty project,where the natural condition is abominable.The beacon foundation has double characteristics of wave wall and independent pile,so the wave force calculation for beacon foundation is quite complicated.Based on the practical engineering,we adopt different specifications and handbooks at home and abroad in the analysis of wave force calculation method for breakwater beacon foundation.Combining with model test result,we propose a recommended wave force calculation method for breakwater beacon foundation under the action of medium-long period wave.To ensure the stability of breakwater beacon foundation and also keep some surplus,we suggest that Morison equation should be adopted for wave force calculation,and Martin equation should be adopted for rechecking the calculation results.The analysis results in this paper can provide a certain references for the similar jetty projects and also for the domestic code revising.
