摘要
笔者同时考虑基于钢筋混凝土粘结滑移及混凝土路面板与地基之间的非线性本构关系,建立了连续配筋混凝土路面(CRCP)在温度荷载作用下的力学模型,以及按接触理论推导的有限元刚度矩阵,得出了有限单元法的数值解,分析了降温荷载作用下路面应力和位移的分布规律.
Based on the nonlinear interactional relation between reinforced steel bar and concrete, and between subgrade and concrete, the CRCP calculation model and the stiffness matrix loading temperature changing are derived based on the contact theory. The numerical solution is obtained. The distribution rule of stress and deformation in CRCP is analyzed.
