| 摘 要： | 结合工程实例以蒙特卡罗分析法为基本出发点,首先通过计算机根据弯沉和弯拉应力的功能函数来生成1000个功能函数的一个随机抽样,然后用大熵法拟合沥青路面的弯沉功能函数的密度函数,求出两种失效模式的失效概率。同时,把整个路段看作是一个由弯沉失效和弯拉应力失效的两种失效模式串联组成的网络系统,对整个系统进行了可靠性评估。

| Abstract: | Based on Monte Carlo analysis method,a random sample of 1000 functions was built according to deflection and bend stress using computer.The density function of deflection function of asphaltum road surface was fitted using entropy method and invalidation probability of two invalidation modes was solved.The whole road section was a network system made up by the two invalidation modes of deflection and bend stress invalidation.The system reliability was evaluated in this paper. |
