评价路网中各路段的使用性能,根据路面使用状况制定养护计划,才能充分利用有限的养护资金,取得最佳养护效果。针对路面使用性能综合评价的复杂性,利用突变级数的基本思想和突变系统常用类型中的蝴蝶突变,建立了高速公路路面的使用性能评价模型。最后以四川省5条高速公路的路面性能评价为例,按其使用性能进行了排序,验证了该评价方法的合理性,为路面性能评价和养护决策提供了一种新方法。
To evaluate the service performance of each section of the road network and formulate the maintenance plan according to the road conditions, we can make the best use of the limited maintenance funds to achieve the best conservation results. According to the complexity of comprehensive evaluation of pavement performance, the utility model of freeway pavement is built by using the basic idea of mutation series and the butterfly mutation in the common type of mutation system. Finally, the pavement performance evaluation of five expressways in Sichuan Province is taken as an example, and their performance is ranked. The rationality of this evaluation method is verified, which provides a new method for pavement performance evaluation and maintenance decision.
