Abstract


The construction of rock-fill dams is rapidly expanding, which sets an even higher demand on construction management and mechanical efficiency. Computer simulation technologies emerge as the times require, which offers an effective analysis method to construction management decisions. It makes construction management move towards a new level.On the basic of systems engineering theories, a numeric computer model of construction process is established. The fill schedules and various quantitative parameters can be computed rapidly by simulating on the construction process.In accordance with the previous all-process static simulation technology which can’t meet the simulation demands under construction, this paper advances a real-time dynamic simulation system. It adopts a dynamic-modeling idea oriented towards discrete events on the basis of project management and simulation theories. After an overall dynamic mathematical model has been established according to the present progress, users can make real-time simulations in this system. The simulation environment supports a various-hierarchy modeling and simulation of construction progress, and it has high credibility because it can reflect the real construction process.This paper brings forth new ideas as follows: Firstly, it establish a comprehensive and dynamic construction model of rock-fill dams on the basis of close system analysis; Secondly, it discusses the key technologies of real-time simulation, such as digital terrain model, the flow of dynamic simulation, data base management system and the application of the cyclic operation network technology; Thirdly, this paper designs the structure and modules of the simulation software which realizes a furthest mutual simulation under the guide of software engineering theory.At last, this paper demonstrates the software development progress of LiYang concrete-facing dam in JiangShu and analyses the simulation results in detail. It illustrates that the method is reliable and applicable.
