摘  要:目的:研究近岸施工防污屏力学性能的安全性。方法:由于防污屏屏体结构透水性能高,且整体扰动主体为上部浮体,因此采用上部浮体不变下部透水屏体等效成系泊缆的方法,建立了防污屏力学分析模型。借助ANSYS软件构建了近海施工环境,选取了共聚物型PP材料防污屏仿真计算分析。结果:通过对其模型进行100 s的仿真,得到了在给定环境下模型的位移、张力等参数的变化曲线,并求得等效屏体的最大张力为2.4×104 N,符合安全规范。结论:为近岸施工防污屏力学性能分析、安全性验证提供了新的分析思路与方法。Aims:This paper studies the safety of the mechanical properties of anti-fouling screens in nearshore construction.Methods:Due to the high water permeability of the anti-fouling screen structure and that the overall disturbance is the upper floating body,a method that combined the fact that the upper floating body was unchanged and the lower water-permeable screen was equivalent to a mooring line was used to establish a mechanical analysis model of the anti-fouling screen.With the help of ANSYS software,an offshore construction environment was constructed;and the simulation calculation and analysis of the copolymer-type PP material anti-fouling screen was selected.Results:By simulating the model for 100 s,the change curve of the model s displacement,tension and other parameters in a given environment was obtained;and the maximum tension of the equivalent screen was 2.4×104 N,which met the safety regulations.Conclusions:It provides a new analysis idea and method for the mechanical performance analysis and safety verification of anti-fouling screens in nearshore construction.
