| 摘 要： | 在路网系统中考虑道路单元的可靠度, 根据道路网络的综合拓扑指标值确定系统中各道路单元的重要程度, 最终确定维修后道路的目标可靠度, 从而利用直接积分法得到沥青加铺层的厚度. 分析表明: 当加铺层厚度小于35 cm 时, 道路可靠度随着加铺层厚度的增加而增加; 当加铺层厚度达到或超过35 cm 时, 道路可靠度随着加铺层厚度的增加而趋于稳定. 考虑单条道路在整个路网系统中的地位, 不仅能够使修护后的路面系统可靠度最大化, 而且可以使修护费用得到最优分配.

| Abstract: | Putting the road unit reliability to the road network system, using comprehensive topological index of the road network to determine the importance of each road unit and then to determine the road reliability after repaired, finally it can get the thickness of asphalt overlay by the direct integral method. The example showed that when the thickness of asphalt overlay is less than 35 cm, the road reliability with thickness of asphalt overlay increases and when thickness of asphalt overlay gets to 35 cm, reliability with thickness of asphalt overlay tends to a stable value. Considering the position of each road unit in the road network can not only make maintained road system reliability maximize, but also make optimal allocation of repair costs. |
