为判断半刚性基层振动压实能否造成下承层的早期破坏，对半刚性基层在移动—振动压实荷载作用下的下承层动态应力响应进行分析。

The dynamic stress response of the lower course by moving-vibrating compaction on semi-rigid base was analyzed to judge whether it caused early wreckage to the lower course.

本文讨论移动荷载下、弹性半空间地基上的刚性道面水泥混凝土加铺层的动态设计理论和计算方法，并试图把此套方法与场道无损检测评估系统结合起来。

Research on theory and methods of the overlay on existing rigid concrete pavements, which is on semi-infinite elastic medium to moving load, is involved in this paper.
