提高现有混凝土路面或机场混凝土道面的承载力,往往采用在旧面层上加铺新混凝土补强层的方法。由于双层路面的工作特性较复杂,所以计算补强层的所需厚度,至今还是采用由试验得出的经验公式。目前用得比较多的计算公式是: h_c=[h~p-ch_e~p]~(1/p) (1) 如果上下两层的混凝土强度不同或相差较多(混凝土的抗弯强度相差7kgf/cm~2以 To improve the bearing capacity of existing concrete pavement or airport concrete pavement, often used in the old surface layer of new concrete reinforcement layer method. Due to the complexity of the working characteristics of the double pavement, the required thickness of the reinforcing layer is calculated, so far, empirical formulas derived from experiments are still used. Currently used more calculation formula is: h_c = [h ~ p-ch_e ~ p] ~ (1 / p) (1) If the upper and lower two layers of concrete strength difference or more difference (concrete flexural strength difference of 7kgf / cm ~ 2 to
