【摘要】：随着斜拉桥跨径的不断增加,新颖结构形式不断涌现,斜拉桥施工控制技术遇到了新的挑战。由于大型斜拉桥工程结构复杂,规模巨大,难以用普通的的手段进行施工控制。因此,研究开发一套智能化的斜拉桥施工控制专家系统,实现斜拉桥施工控制自动化和智能化,将大幅提高斜拉桥施工控制的科学性、可操作性和可靠性。解释机制是专家系统的重要组成部分,除了说明问题求解过程外,还起着证实系统结论、辅助系统调试甚至获取知识的作用。本文在以往桥梁施工控制专家系统研究的基础之上,对斜拉桥智能施工控制专家系统解释机制进行了研究。全文主要研究内容如下:(1)分析了斜拉桥施工控制目的、意义、内容和方法;总结了专家系统解释机制研究现状和存在的问题;概述了斜拉桥智能施工控制专家系统理论,并阐述了斜拉桥智能施工控制专家系统中的知识库、数据库、推理机和解释机制。(2)建立了斜拉桥智能施工控制专家系统解释机制理论体系;研究了智能专家系统中解释作用、用户模型表达方式等理论。用户模型表示方法有人为分级、确定性因子、复杂性和重要性因子、模糊用户模型;解释机制表达方式包括预制文本法、追踪解释法、策略解释法和自动程序员法;提出了解释的交流方式:文本解释、图形解释和事例解释;提出了斜拉桥智能施工控制专家系统解释机制实现策略。(3)采用Java开发了斜拉桥智能施工控制专家系统解释器。实现了知识库、数据库、控制决策、解释咨询等子系统的开发。该解释器实现了系统各功能模块的预定功能。(4)软件应用到湖州市创业大桥施工控制过程中,实现了对监测数据管理、知识解释、控制决策的运用和解释以及解释咨询。控制过程及结果表明,解释器达到了理想的效果。
[Abstract]:With the increasing span of cable-stayed bridges and the emergence of new structural forms, the construction control technology of cable-stayed bridges is confronted with new challenges.Because of the complex structure and large scale of large cable-stayed bridge, it is difficult to carry out construction control by ordinary means.Therefore, the research and development of an intelligent construction control expert system for cable-stayed bridge, to realize the automation and intelligence of cable-stayed bridge construction control, will greatly improve the scientific nature, maneuverability and reliability of cable-stayed bridge construction control.Explanation mechanism is an important part of expert system. In addition to explaining the process of solving the problem, it also plays the role of confirming the conclusions of the system, assisting the debugging of the system and even acquiring knowledge.Based on the previous research on the expert system of bridge construction control, the interpretation mechanism of intelligent construction control expert system for cable-stayed bridge is studied in this paper.The knowledge base, database, inference engine and explanation mechanism of intelligent construction control expert system of cable-stayed bridge are expounded. The theoretical system of interpretation mechanism of intelligent construction control expert system of cable-stayed bridge is established, and the interpretation function of intelligent expert system is studied.Theory of user model expression.User model representation includes hierarchical, deterministic, complexity and importance factors, fuzzy user model, prefabricated text method, traceability interpretation method, policy interpretation method and automatic programmer method.The communication mode of interpretation is put forward, including text interpretation, graphic interpretation and case interpretation, and the implementation strategy of intelligent construction control expert system interpretation mechanism of cable-stayed bridge is put forward. (3) the intelligent construction control expert system interpreter of cable-stayed bridge is developed with Java.The development of knowledge base, database, control decision, interpretation consultation and so on is realized.The interpreter realizes the predefined function of each functional module of the system. The software is applied to the construction control process of Huzhou Venture Bridge. It realizes the management of monitoring data, the interpretation of knowledge, the application and interpretation of control decision, and the interpretation consultation.The control process and results show that the interpreter achieves the ideal effect.
