Continuously Reinforced Concrete Pavement End Anchor Structure

In this paper, the expansion force in the anchored end of the continuously reinforced concrete pavement (CRCP) caused by the rise of the temperature is calculated with section iterative method, and the colTesponding calculation program is edited, and the influence of the allowable movement of the end, the linear expansion coefficient of the concrete and other parameters are analyzed. Finite element method and matrix method are used respectively to analyze the stress and distance of the transverse trench lugs, the comparison between calculated and measured values shows that these two methods are feasible and the influence of some parameters, such as the height of the lugs, the elastic modulus of subgrade is analyzed. The method of evaluation of comprehensive effect coefficient for lateral bearing capacity of pile group is used to analyze the cast-in-place concrete piles. At last, the corresponding design methods are brought out according to the different end anchorage system of CRCP.
