在车辆行车荷载作用下,桥面铺装层的破坏主要有两种形式,即铺装层内部产生较大的剪应力而产生的剪切变形和抗水平剪切能力较差而产生水平方向上的剪切变形。为了探究水泥混凝土桥桥面铺装层的破坏机理,运用ANSYS三维有限元软件计算分析水泥混凝土桥混凝土铺装层的最大剪应力,从水泥混凝土的铺装层厚度、混凝土的弹性模量和行车荷载三个方面出发,研究了对水泥混凝土桥桥面铺装层的受力特性。
Under the action of vehicle driving load, there are mainly two kinds of damage to the deck pavement, namely, the shear deformation caused by the large shear stress in the pavement and the poor resistance to horizontal shearing, resulting in the horizontal direction Shear deformation. In order to explore the failure mechanism of the bridge deck pavement of cement concrete bridge, the maximum shear stress of the concrete pavement of the cement concrete bridge was calculated and analyzed by using the three-dimensional finite element software ANSYS. From the concrete pavement thickness, concrete elastic modulus and driving Load from three aspects, studied the cement concrete bridge deck pavement stress characteristics.
