摘　　要：根据连续配筋混凝土路面板扭转等效原则,转换了板横向裂缝处车辆集中荷载的作用模式。采用弹性薄板理论,提出了车辆集中荷载作用下脱空的连续配筋混凝土路面板的扭转角与扭转位移计算公式,并采用有限元分析结果对公式计算值进行了对比验证,可供工程技术人员参考。According to the equivalence principle of distortion displacement,the action model of the concentrated vehicle load which acted on the CRCP transverse crack was translated.With the small deflection theory of elastic thin plates,the distortion displacement formulas of CRCP under the concentrated vehicle load were put forward.The calculating results of formulas were compared and verified by using finite element method,which can give some practical values to engineers.
