摘　　要：建立了土石方开挖数学模型,将开挖过程简化为相应的数学问题,利用数学理论进行分析和研究,为土石方分区分层分块开挖原则提供了科学的方法和理论的指导。讨论了土石方开挖仿真系统的组成、统一建模语言(Unified Modeling Language,UML)的建模机制,提出了一种基于UML土石方开挖仿真系统的建模方法,并利用RationalRose工具对其进行面向对象的可视化建模,详细阐述了系统用例模型、静态模型和动态模型的建模过程。实例分析说明了土石方开挖数学模型、UML建模机制是有效的、可行的。The mathematical model of earth-rock excavation is buih.h simplifies the process of excavation for the corresponding mathematical problems with mathematical analysis and theoretical studies.The scientific method and theory for the principles of earth-rock hierarchical,divisional and blockwise excavation is provided.h analyzes the composing of the earth-rock work simula- tion system and the modeling mechanism of Unified Modeling Language（UML）.A modeling method of Excavation Simulation System （ESS） for the earth-rock work based on UML is discussed.The visual modeling procedure of object-oriented for earth-rock work is elaborated by using software of rational rose in this paper,such as system ease modeling,static modeling and dynamic modeling.A case shows that the simulation method and modeling mechanism of UML are effective and feasible.
