通过理论计算和数值分析，对钢筋混凝土盖板承载力评估中的主要参数分别进行计算对比。结果表明：在计算钢筋最大拉应力和混凝土最大压应力时，理论计算和数值分析的计算结果基本一致，最大误差只有4％，两种计算结果均可采用。但是在计算中性轴最大剪应力和最大裂缝宽度时，两种方法的计算结果误差较大，最大比重达到了23％，因此应以按照行业规范进行的理论计算结果为准。

This thesis calculates the main parameters of the assessment of the bearing capacity to rein-forced concrete cover and compares the results of the calculations .It shows that the solution of theoretical calculations and numerical analysis are basically consistent when calculating the maximum tensile stress of steel bar and the maximum compressive stress of concrete .The maximum error is only 4%—the results of two calculations can be employed .However ,when the maximum shear stress of the neutral axis and the maximum crack width are calculated ,the error of the two calculation results is large —the maximum error is 23%.Therefore,the solution of theoretical calculations according to the tindustry norms should be cal-culated.
