摘要: 纤维增强复合材料具有轻质高强、可设计性强、耐候性好等特性,可用于桥梁防船撞领域。本文针对纤维增强复合材料缠绕管桩进行了桥梁隔离式防撞系统的研究。对纤维增强复合材料缠绕管桩构件开展了抗弯试验,对比分析了不同纤维缠绕角度和管壁厚度对管桩受弯破坏模式及其力-位移曲线的影响。基于弯曲试验结果,计算了缠绕管桩的弹性模量,根据理论计算设计出悬臂桩和支撑桩两种受力形式的单根防撞管桩,继而给出了排架式管桩防撞系统的设计建议。

Abstract: Fiber reinforced composites have the characteristics of light weight, high strength, good designability, good corrosion resistance, and can be used in the field of bridge anti-collision. In this paper, the isolated anti-collision system of bridge was studied for the fiber reinforced composite winding pipe pile. Bending tests were carried out on fiber reinforced composite winding pipe piles, and the failure modes and force-displacement curves of the winding piles under different winding angles and thicknesses were compared and analyzed. The elastic modulus of the winding pipe pile was calculated according to the test results, and according to the theoretical calculation, a single anti-collision pipe pile with cantilever pile and support pile is designed, and then some design suggestions for anti-collision system of the bent pipe pile were provided.

Key words: fiber reinforced composite, winding pipe pile, bridge anti-collision, bending test, theoretical analysis
