摘要

近年来风暴潮等海洋灾害的频发,对沿海大型工程的防御能力提出了更高的要求。本研究结合广西北海港石步岭港区项目海岸防御工程的设计标准及现状,进行风暴潮和海浪灾害的风险性评估,把推算得到的防御工程应达到的理论顶高程与实测高程进行对比,评估该工程项目抵御海洋灾害的能力。研究发现考虑海平面上升之后的极端高潮位评估结果跟设计值相当;无论是设计高潮位还是极端高潮位下的N向波高的理论值均高于设计值;码头及其他防护岸段的实测最低高程均低于考虑波浪爬高影响之后的理论顶高程,存在一定风险,建议项目业主单位立即采取措施以降低海洋灾害风险。

Abstract

Higher demand of coastal large-scale projects defense capacity should be put forward together with the frequent marine disaster (MD) such as storm tide. This study investigated the design standard and status quo of Guangxi Beihai Port Shibuling Harbor Project in the coastal defense project (CDP), analyzed the design standard and parameters of storm surge and ocean waves, and evaluated the MD defense capacity of each section by comparing the right theoretical CDP elevations with the measured ones. Results show that evaluation result of extreme high tide level in consideration of sea level is equivalent to the preliminary design value. Theoretical results of waveheight in the north direction are greater than the designed values. The measured minimum elevation in both wharf sections and other CDP ones are lower than the evaluation values considering the wave run-up impact, which carries some risks. Some requisite measures should be immediately adopted to deduct MD risk.
