某离岸人工岛平面方案论证*

在分析水文泥沙资料的基础上,采用海岸地貌、潮流数值模拟、物理模型试验等技术手段,对建于粉砂质海岸的某离岸人工岛平面方案进行研究论证.研究结果表明,人工岛的建设对流场的影响范围仅限于岛南北侧500 m和东西侧1 500m范围之内,平面布置与潮流、波浪相适应,所采取的护岛潜堤、长短平护等防护措施有效,平面布置方案合理可行.

On plane program of offshore artificial island

This paper, which on the basis of analysis of hydrology and sediment data, uses the numerical simulations of coastal landforms and tidal current, physical model tests and other technical means to research the plane program of an offshore artificial island on the silty shore. The study result indicates that the impact of the artificial island on flow field is restricted within a scope of 500 m to the south and north as well as 1 500 m to the east and west. The island layout is adapted to the tidal current and wave conditions, while the island protection measures,such as submerged protecting dike, long and short bed protections, etc., are effectively applied, and thus the layout scheme is appropriate and feasible.
