基于通行覆盖率的机场道面交通量分析

摘要

通过对不同起落架机型的轮迹分布规律进行测试,得出机场道面荷载覆盖作用曲线,同时引入通行覆盖率理论,介绍了机场道面通行覆盖率的计算原理,并以B747-400为例,对其单轮及双轮叠加轮迹的正态分布曲线的最大概率值进行了计算,最后,计算得到其通行覆盖率P/C为4.25,该方法对我国机场道面设计方法革新具有重要的推动作用.%This paper established traffic distribution curve based on tests of various landing gear, proposed the concept of cover to pass ratio and probed the calculation of the cover to pass ratio,in the case of,taken B747- 400 as an example. Calculated the most probability value of single wheel and double wheels superposition of coverage curve, and concluded the final P/C value is 4. 25, the pavement design method is constructive to the current airport pavement design.
