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.
