摘要:

为有效解决传统钢桥面病害,提出了钢-聚酯型聚氨酯(钢-PPUC)混凝土组合桥面板结构,开展了正交异性钢桥面板的疲劳性能研究。以马鞍山公铁两用大桥为工程背景,建立局部有限元模型,采用热点应力法获得车轮荷载作用下钢桥面易疲劳开裂部位的应力响应,基于疲劳应力幅进行疲劳强度评估。考虑不同温度、不同铺装层厚度和不同结构形式条件下PPUC铺装层对正交异性钢桥面板疲劳性能的影响。结果表明:高弹性模量的PPUC铺装层对正交异性钢桥面板典型疲劳细节处的应力具有明显的改善作用; 顶板与纵肋连接部位疲劳细节应力幅降幅最大,顶板与纵肋连接处桥面板细节、纵肋与横隔板连接处纵肋细节和纵肋对接焊缝细节均满足抗疲劳开裂要求; 不同温度作用下的弹性模量变化对典型疲劳细节等效应力幅的影响是非线性的,铺装层厚度变化对典型疲劳细节等效应力幅的影响是近似线性的; 为兼顾正交异性钢桥面板受力性能和行车舒适性两方面要求,提出了单层和双层复合型PPUC结构形式,计算得到2种结构形式对各疲劳细节应力幅最大降幅为21%～56%,最小降幅为8%～36%,为钢-PPUC组合桥面板抗疲劳设计提供理论依据。

Abstract:

In order to effectively solve the diseases of traditional steel bridge deck, the steel-polyester polyurethane concrete(steel-PPUC)composite bridge deck was proposed, and the fatigue performance of the orthotropic steel bridge deck was studied. The local finite element model was established based on Ma'anshan dual-purpose highway and railway bridge. The hot spot stress method was used to obtain the stress response of the steel bridge deck which was prone to fatigue cracking under the wheel load. The fatigue strength was evaluated based on the fatigue stress amplitude. The influence of PPUC pavement on the fatigue performance of orthotropic steel bridge deck was considered under the conditions of different temperatures, different pavement thicknesses and different structural forms. The results show that the PPUC pavement with high elastic modulus can significantly improve the stress of typical fatigue details of orthotropic steel bridge deck. The stress amplitude of the fatigue details at the connection between the top plate and the longitudinal rib is the largest. The details of the bridge deck at the connection between the top plate and the longitudinal rib, the longitudinal rib at the connection between the longitudinal rib and the diaphragm, and the butt weld of the longitudinal rib all meet the requirements of anti-fatigue cracking. The influence of elastic modulus change caused by different temperatures on the equivalent stress amplitude of typical fatigue details is nonlinear, and the influence of pavement thickness changes on the equivalent stress amplitude of typical fatigue details is linear. In order to meet the requirement of the mechanical performance of orthotropic steel bridge deck and the driving comfort, single-layer and double-layer composite PPUC structures are proposed. The maximum reduction of the stress amplitude of each fatigue detail of the two structures is calculated to be 21%-56%, and the minimum reduction is 8%-36%, which provides a theoretical basis for the anti-fatigue design of steel-PPUC composite bridge deck.
