摘　　要：为了合理确定军用机场水泥道面预养护最佳时机,在分析现有公路路面和机场道面性能模型的基础上,建立了军用机场道面破损指数与国际平整度指数之间的关系式,结合军用机场水泥道面破损指数衰变模型和破损指数-国际平整度关系式,得到了军用机场水泥道面预养护最佳时机决策模型。基于目前我军仍然主要采用三米直尺进行平整度测试的现状,在大量实测数据的基础上建立了三米直尺平均间隙与国际平整度指数相关关系式,实现了二者之间的转换。基于军用机场水泥道面性能检测数据积累较少的现状,采用空间代时间的方法,对我军使用环境相近的若干个水泥道面的破损状况和平整度数据进行了拟合分析,验证了预养护最佳时机决策模型的正确性,得出了模型的具体参数。通过对破损指数-国际平整度关系式进行二次求导寻找道面破损指数衰变最快的唯一临界值,再由破损指数衰变模型求出该值所对应的使用年限,即为最佳预养护最佳时机。In order to reasonably determine the best time for preventive maintenance of cement concrete pavement at military airports, the relationship between the pavement damage index and IRI is established on the basis of the analysis of the existing highway and airport pavement performance model. The decision model of preventive maintenance time for cement concrete pavement of military airport is obtained, combined with the pavement damage index decay model and the damage index-IRI relationship. Based on the current situation that our army still mainly uses the three-meter ruler to test the roughness and a large amount of measured data, the correlation between the IRI and the average clearance of the three-meter ruler is established. Based on the fact that the performance data of cement concrete pavement in military airport accumulate less, the damage status and flatness data several airport cement concrete pavements with simi-lar service environment to our army fitted and analyzed using the method of space generation time. The correctness of the preventive maintenance timing model has been verified, and the specific parameters of the model have been obtained? It can be found that the fasted decay threshold of the damage index, unique to that exists, by the damage index-IRI relationship. Then the damage-decay model is used to find out the useful life of this value, which is the best preventive effect maintenance time.
