To guarantee the berthing conditions,mitigate the impact of engineering on the surrounding shoreline,and reasonably reduce the engineering investment,we study the layout of breakwater in Lufeng marine base wharf project. Based on wave and tidal current observation data and historical data of remote sensing images,and carrying out the numerical simulation of wave,tidal current,sediment and beach evolution,we analyze the hydrological characteristics of Lufeng marine based,clarify the berthing stability conditions,wave loads,flow field changes,sediment movement and shore evolution characteristics under different breakwater layout schemes,and discuss the advantages and disadvantages of them.According to the comparative analysis,and considering the convenience of reserving more expansion space and phased construction,we suggest to adopt the northeast opening scheme and do not extend the breakwater currntly,and supplement the affected bank with corresponding beach regulation measures.
