| 摘 要： | 本文将飞机－道面－土基作为一个相互作用的动力系统，对飞机滑行情况下，弹性半空间地基上刚性道面板的动响应，采用有限元法进行了计算分析。结果表明，本文计算结果与现场实测值吻合很好。由于考虑了飞机和道面之间的耦合作用，避免了实测飞机对道面作用荷载的繁琐工作，因此本文方法具有明显的实用意义。

| Abstract: | In this paper,the author combines aircraft,pavement and soil as a dynamic couplingsystem. Using FEM,the dynamic responses of the rigid pavement based on elastic half spaceare calculated while aircraft is running on the pavement.The results are shown to be quitegood compared with the results of airfield test.Because the interactions between aircraft andpavement are discussed,the aircraft loads are avoided.The theory of this paper is effectiveto solve the problems of airfield engineering. |

| Keywords: | aircraft pavement dynamic response interaction elastic half space |
