为了准确计算连续配筋混凝土路面在温度作用下整个路段任意点的位移和应力,基于钢筋混凝土间粘结滑移效应,考虑地基摩阻力的影响,采用接触有限元理论建立了连续配筋混凝土路面的刚度方程,得出了考虑各个裂缝间隔段和锚固地梁之间联合作用的整个路段各部分应力和位移的有限元解。通过具体算例,研究了连续配筋混凝土路面在温度应力作用下的钢筋与混凝土各部分的位移和应变的分布情况。计算结果表明,若采用裂缝处钢筋位移为零的假设条件显得不尽合理,温度梯度的影响不可忽略,靠近端部的锚固地梁位移和内力最大。
In order to accurately calculate the displacement and stress of continuous reinforced concrete pavement at any point of the whole section under the action of temperature, based on the effect of the bond slip between reinforced concrete and considering the influence of the foundation friction, a continuous reinforced concrete pavement , The finite element solutions of stress and displacement of all sections of the whole section considering the joint action between each fracture interval section and anchored ground beam are obtained. Through the concrete example, the displacement and strain distribution of the reinforced concrete and the concrete under the temperature stress are studied. The calculation results show that if the assumption that the displacement of rebar at the crack is zero is not reasonable, the influence of temperature gradient can not be neglected, and the displacement and internal force of anchor beam near the end are the largest.
