Mechanical Behavior Analysis of Different Types of Continuously Reinforced Concrete Pavement Effected By Temperature Dropping
In order to calculate the stresses and displacements under temperature loads in any spots of the whole highway section on CRCP, considering the influence of frictional resistance of the foundation and the effect of bonding-slip between steel and concrete, the contact finite element theory is adopted to formulate the CRCP rigid equation. As a result, the finite element solution of stress and displacement of any point on the pavement is obtained, taking the combined effects of all sectors between cracks under different real state in consideration. According to specific examples, the study on the distribution of stress and displacement of any point in the whole road area is carried out when CRCP is under the temperature loads. The end displacement and the length of anchorage under different parameters to the end free CRCP is calculated. The result shows that the different anchorage forms have great effect on the calculated results near the end of CRCP, while little effect on the mid segment of road. Considering the synthetically effect was observed, consequently, it is necessary to analyze the CRCP according to the actual condition. The crack width and the stress in the area of end anchorage effected by the temperature dropping can be calculated. The subgrade friction coefficient is the major factor to the end anchor force and displacement. The bigger subgrade friction coefficient is, the more favorable the end of CRCP is.
