摘要:
为研究超载作用下装配式梁桥横向联系的疲劳损伤程度,基于线性累积损伤准则建立装配式梁桥横隔梁钢板连接构造的疲劳评估流程. 以某混凝土梁桥为工程背景,开展车辆超载对混凝土梁桥横向联系疲劳损伤的影响研究,分析过桥重车超载比例、超载率、车载作用频次、装载水平和超载车型等因素对连接构造疲劳损伤的影响规律. 结果表明:随着超载率增加,横向联系疲劳寿命显著降低;相对车辆一般运行状态,密集运行状态下横向联系的疲劳寿命对超载率变化更为敏感;相较于超载率和车辆作用频次,横向联系疲劳损伤对车辆超载比例和装载水平更为敏感;不同超载车型对横向联系疲劳损伤的影响差异明显,其中,四轴整车与六轴挂车的超载对横隔梁连接钢板的疲劳损伤影响最为突出. 严格控制实际交通超载车比例和重车装载水平,可有效延缓关键构件疲劳损伤进程,桥梁限载管理中应考虑超载车型对桥梁构件疲劳寿命影响的差异.
Abstract:
In order to study the fatigue damage degree of the transverse connection of prefabricated assembled beam bridges under overloading, we establish the fatigue evaluation process of the steel beam connection structure of the fabricated beam bridges based on the linear cumulative damage criterion. Taking a concrete girder bridge as an example, we investigate the influence of vehicle overload on the lateral contact fatigue damage of concrete girder bridge and analyze the factors such as overload ratio, overload rate, vehicle frequency, loading level and overload model. The results show that the fatigue life of transverse connection decreases significantly with the increase of overloading rate. Compared with the general running state of vehicles, the fatigue life of horizontal connection is more sensitive to the change of overloading rate. Compared with overloading rate and vehicle action frequency, the lateral contact fatigue damage is more sensitive to vehicle overload ratio and loading level. The influence of different overload models on the fatigue damage of transverse connection is obvious, among which the overload of four-axle vehicle and six-axle trailer has the most prominent influence on the fatigue damage of the steel plate connected with the transverse diaphragm beam. Strictly controlling the proportion of overloaded vehicles and the loading level of heavy vehicles can effectively delay the fatigue damage process of key components. The bridge load limit management should consider the difference of the impact of overloaded models on the fatigue life of bridge components.
