Design and Verification of Precast Cement Concrete Pavement Joint with Clamping Ring Connected Dowel Bar
摘要
Abstract
For detachable precast cement concrete pavement,a joint with clamping ring connected dowel bar is proposed.Based on expounding its structural characteristics and basic parameters,the deflection load transfer coefficient and deflection difference are selected as indexes,and the finite element method is used to analyze the influence of the parameters of the lower opening groove,the transmission rod,and the clamping ring on the load transfer ability of the joint with clamping ring connected dowel bar.Meanwhile,the varying regularity of the elements and the interface stress of the clamping ring connected dowel bar joint is analyzed,and reasonable structural parameters are obtained.Furthermore,the load transfer performance of the clamping ring connected dowel bar is evaluated by indoor full-scale test.The results show that the load transfer capacity of the proposed joint with clamping ring connected dowel bar meets the requirements,which has certain engineering practical value.关键词
