| 摘 要： | 针对现有CRCP温度应力分析方法不能充分反映CRCP真实受力条件的弊端,提出了考虑CRCP各板段实际受力情况的全路段整体迭代思路。通过对CRCP微分单元的分析,推导了考虑钢筋与混凝土间及混凝土与地基间非线性粘结-滑移关系的温度应力通用解析解。利用该解析解,在全路段范围内进行迭代求解,可以计算CRCP内任一点由温度变化所引起的应力、位移。 |

| Abstract: | Given the drawbacks of the existing analysis method for thermal stress of CRCP which can't reflect it's actual boundary condition,a whole road section iterative method which can reflect actual boundary condition of each slab section is presented in this paper.Based on the analysis of CRCP differential cell,a general analytic solution considering nonlinear bond-slip relation between steel bar and concrete and that between concrete and base is deducted.Iterative method is used for the whole road section to find out analytic solution and stress and displacement caused by temperature change in any point of CRCP can be calculated. |
| Keywords: | Continuously Reinforced Concrete Pavement(CRCP) boundary condition thermal stress analytic solution |
