高土石坝施工计算机一体化仿真

Computer Integration Simulation for High Rockfill Dam Construction

采用系统仿真方法对土石坝施工中的两个子系统,即运输上坝子系统和坝面填筑子系统的施工过程进行系统描述,分析了各自的运行特点,阐明内在联系,提出将二者有机结合起来进行一体化仿真.拓展了循环网络模型的概念,精减了现有循环网络模型中的职能节点和控制节点,并增设了一种新的综合节点,实现了面向资源的施工系统仿真建模.编制了仿真软件,并在某高土石坝施工设计中得到应用,仿真成果验证了该建模的有效性及仿真方法的先进性.

Construction processes of two subsystems in rockfill dam are described in detail. They are haul and placement of rip-rap subsystem, which are interactional. An integration simulation is proposed to combine these two subsystems, and it impersonally demonstrates actual construction. Cycle Operation Network (CYCLONE) is used to build construction model for rockfill dam. With construction specialty, the conception of CYCLONE model is expanded. Compared with the existed model nodes, a new synthesis node is introduced while function and control nodes are deleted. It realizes system simulation construction model that faces resource.A simulation software for construction of rockfill dam is programmed and its application to an actual rockfill dam shows the software′s efficiency and practicability.
