薛家岛湾沉积动力学特征及海港开发研究

STUDY ON THE SEDIMENT DYNAMIC CHARACTERISTICS AND HARBOUR DEVELOPMENT OF THE XUEJIADAO BIGHT IN JIAOZHOU BAY,YELLOW SEA

于1990年秋对胶州湾内的薛家岛湾进行海洋水动力条件及沉积动力学特征、泥沙运动规律研究，为开发建设港口提供科学依据。结果表明，湾内水深大于1m的海底泥沙发生“全面移动”的时间，一年内仅有1-2d，其余处于稳定状态或“表面移动”状态。湾内泥沙来源很少，预计建港后，港池和航道年平均回淤量分别小于16cm和10cm，对于开发中小型港口十分有利。

Xuejiadao Bight is in the southern part of Jiaozhou Bay, Yellow Sea. In order to develop the harbour, its marine hydrodynamics, sediment dynamic properties and sand transport processes were investigated in Autumn 1990. The results showed 'Whole sand movement' on the bottom of more than 1'm water depth lasts 1-2 days in a year and steady or 'surface sand movement' elsewhere. The sources of sand are rather limited and average siltation amount in the harbour and channel is less than 16cm and locm respectively after establishing the harbour, and very favou-able for further out of middle, and small harbours.
