采用ABAQUS有限元分析软件,分别建立斜向和垂直布筋的预应力水泥混凝土路面结构的三维有限元模型,通过改变温度的方法对路面施加预应力。分别得出了斜向布筋和垂直布筋的预应力水泥混凝土路面在标准轴载作用下的力学行为,通过这两种结果的对比得出:斜向布筋有效地减小了板体底面的起伏变化,使板体整体平整性较好,荷载影响范围小。这些研究成果为日后预应力混凝土路面板在国内的研究和设计提供了相应的参考和依据,有助于加速中国预应力混凝土路面板的研究进程。
ABAQUS finite element analysis software was used to establish the three-dimensional finite element model of prestressed cement concrete pavement with oblique and vertical reinforcement respectively. Prestressing was applied to the pavement by changing the temperature. The mechanical behaviors of prestressed cement concrete pavement with oblique reinforcement and vertical reinforcement are obtained respectively under the standard axial load. The comparison between the two results shows that: the oblique reinforcement can effectively reduce the bottom of the plate Of the ups and downs of the plate body to make the whole formation is better, the impact of load range. These research results provide reference and basis for future research and design of prestressed concrete pavement slabs in China, and help to speed up the research process of prestressed concrete pavement slabs in China.
