连续配筋混凝土路面干缩应力分析

Analysis of Shrinkage Stress of Continuously Reinforced Concrete Pavement

通过建立连续配筋混凝土路面在干缩作用下的应力分析模型与解析解,分析了不同端部条件、混凝土干缩应变、地基摩阻系数和钢筋混凝土粘结滑移系数对连续配筋混凝土路面应力的影响,结果表明,端部半自由的解析与实际路面情况更加相符,混凝土干缩应变、地基摩阻系数和钢筋混凝土粘结滑移系数是影响连续配筋混凝土路面开裂的关键参数。

Based on the stress analysis model and analytical solution of continuously reinforced concrete pavement under dry shrinkage,the effects of different end conditions,concrete shrinkage strain,foundation friction coefficient and reinforced concrete bond slip coefficient are analyzed.The results show that the semi-free analysis of the end is more consistent with the actual road conditions.The shrinkage strain of the concrete,the friction coefficient of the foundation and the bond slip coefficient of the reinforced concrete are the key parameters that affect the cracking of the continuous reinforced concrete pavement.
