累积分布函数

Proper combinations of number of outcomes, discrete step size, and scaling of the random variable, the discrete cumulate percentage distribution and discrete percentage density will converge to the continuous cumulative probability distribution and probability density function respectively.

适当之出现或试验次数或取样数量、散化阶梯大小、随机变数缩放比例可使离散累积百分比分布及离散百分比密度趋近于连续的累积机率分布及机率密度函数。

Fourth, according to the Weibull distributing functions of equivalent loads, calculated the max loads by expanded sample method, acquired eight routine loads spectrum of each roads taking advantages of the Connover classification method, calculated the respective enhancement coefficient in principle of amended Miner linear accumulated fatigue damage rule, by the comparative norm of general tar-paved road, educed the mathematical model of calculating enhancement coefficient of synthesized roads.

第四，根据各路面的等效载荷的Weibull分布函数采用扩展样本法求得了各路面的极值载荷，按照Connover的分级法得到了各路面的八级程序载荷谱。以一般沥青公路为比较基准，采用修正的Miner线性累积损伤理论，根据前桥的S-N和P-S-N关系式得到了各路面的强化系数，建立了综合路面的强化系数计算的数学模型。
