摘    要:根据系列模型方法研究,通过建立模型沙与原型粘性沙之间的关系,确定系列模型试验比尺。利用珠江口伶仃洋海域实测水文、泥沙及水深测量等现场实测资料分析,根据系列模型理论基础,建立人工岛局部动床系列模型,研究工程实施后对人工岛周边的冲刷尺度。研究表明:人工岛上、下游水深变化较小,人工岛东西两侧水深变化较大,距离人工岛较近处,水深增长较大,距离人工岛越远,水深增长越小。人工岛的实施引起的冲刷均集中在人工岛周边1 km左右,范围较小,基本不会对伶仃航道和铜鼓航道产生不利影响。

关 键 词:人工岛  冲刷  系列模型  港珠澳大桥

Abstract:Based on the study of basic theory of series models,the relationship between model sediment and prototype sediment was established,and then the model test scales were determined.On the basis of measured data of the hydraulics,sediments and water depth in Lingding Sea and the study of series models using model sediment,the physical series models on movable bed was founded to study the influence of the construction of the Hong Kong-Zhuhai-Macao Bridge(HZMB) project on the scouring depth.The results show that the water depth has a little changes upstream and downstream of the island and big changes at two sides of the island,and it increases largely near to the island and increases little far from the island in the east and west of the islands.The scouring locations are concentrated on the area inside 1 km from the island,so the construction of the artificial islands could not have any disadvantages influence on the Lingding Channel and Tonggu Channel.
Keywords:artificial island  erosion  physical series model  Hong Kong-Zhuhai-Macao Bridge
