Structural Ultimate Strength Analysis of Anti-Collision Facility of Yinzhou lake Bridge Under Vessel-Generated waves

Under the condition of complex waters, the long-term action of a vessel-generated wave makes the anti-collision facilities have the risk of structural failure. Taking the Yinzhou lake bridge pier anti-collision structure as the research object, the extreme vessel-generated wave load is calculated, and the structural strength of the floating anti-collision facility under the action of the vessel-generated wave is analyzed using the direct calculation method. The results indicate that the ultimate strength of the overall structure of the anti-collision facilities meets the design requirements, but there is insufficient strength in some parts. A strengthening scheme to meet the design requirements of structural yield strength is proposed.
