根据青岛汇泉湾内沙坝形态特征和动力条件的分析,提出汇泉湾内沙坝的形成主要与外海传来的大涌浪有关。通过波浪折射绕射的分析和破波波高,破碎水深的计算得到证实。并解释了沙坝的成因,形态特征及其与波浪变形的对应关系。 According to the analysis of the morphological characteristics and dynamic conditions of the sand bars in Huiquan Bay, it is proposed that the formation of sand bars in the Huiquan Bay is mainly related to the large surges coming from the open sea. Through the analysis of wave refraction diffraction and the high breaking wave, the calculation of broken depth is confirmed. It also explains the causes and morphological characteristics of sandbars and their correspondence with the wave deformation.
