摘要
基于连续配筋混凝土路面板挠度等效原则,转换了板中车辆集中荷载时的荷载作用模式。运用弹性薄板理论,推导出车辆集中荷载作用于板中时脱空的连续配筋混凝土路面板的挠度计算公式,同时运用有限元挠度计算结果对理论公式挠度计算结果进行了对比验证,两者基本吻合。
According to the equivalence principle of continuously reinforced concrete pavement slab deflection, the action mode of concentrated vehicle load in the slab is converted. With elastic thin plate theory, the formula calculating the deflection of holiow continuously reinforced concrete pavement slab under concentrated vehicle load is proposed, then the calculation result by this theoretical formula is compared to that by FEM for verification. Both are basically dovetailed.
