【摘要】 桥面铺装是桥梁行车体系的重要组成部分,它对桥梁耐久性、保证行车安全舒适以及经济效益和社会效益有着极其重要的作用。采用通用有限元分析软件ANSYS程序对某钢筋混凝土桥面柔性铺装层进行力学分析,着重研究了转弯及制动条件下沥青混凝土铺装层的应力、应变和变形分布的变化规律,从而为减少桥面铺装层的早期病害,提高桥面铺装层的服务性能提供理论依据。更多还原

【Abstract】 Pavement on bridge is an important part of vehicle system,and it plays an important role not only in bridge durability,vehicle safety and comfortable level but also in economic benefit and social benefit.In this paper,the mechanical property of a concrete bridge is analyzed by using Finite Element Method.And the distribution of the stress,strain and deformation in the asphalt concrete surfacing under the condition of turning and braking are mainly studied.The analysis result can provide theoretical basis for decreasing early damage and improving the service performance.更多还原
