Abstract: In this paper an attempt is made to present a relationship of mechanical movement in fill construction system. This system is made up of four parts. an excavator, tippers, a bulldozer and a roller. The attempt is based on the knowledge of the probability and the mathematical statistics. The probability model is set up.

Key words: excavator, tipper, bull dozer, systems state, probability

摘要： 本文从概率论与数理统计的基础知识出发,在对路基填方施工中由挖掘机、自卸汽车、推土机、压路机等机械所组成的填方施工系统进行了必要的分析后,建立了该系统机械运行状态的概率模型,揭示了机械运行的一些规律,为机械的配备提供了一种理论依据。
