摘　　要： 在粤东汕尾寮嘴口岬间海滩冲流带设置两条剖面,利用2003年10月13日一个潮周期实测高频剖面数据(采样间隔为1min和6min),分析了海滩的高频振动特征。并结合同期实测碎波带水位波动,探讨了海滩高频振动的动力原因。分析表明,此海滩过程主要以堆积为主,并表现有显著周期的振动;其日内变化受潮汐控制,表现为涨潮堆积、落潮侵蚀;波能对海滩高频振动过程有着重要的影响。 Two profiles were set in the swash zone of the beach between the headlands in the Liaozuikou Bay in Shanwei, Eastern Guangdong Province, in October 13, 2003. Based on the measured high-frequency profile data in one tide period ( sampling frequency is one minute and six minutes ) and wave date synchronously in the surf zone, high-frequency oscillation of the beach is discussed. The analyses indicate that the beachface oscillation in one day is dominated by the tide level and the waves energy is important to the variation of beach too.
