【摘要】：斜拉桥施工控制是斜拉桥施工过程中的关键技术问题。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中的推理机制进行了研究。全文主要研究内容如下:(1)详细分析了桥梁专家系统与系统推理机制的研究现状,总结了目前桥梁专家系统存在的问题;分析了斜拉桥智能施工控制专家系统的结构和组织形式;针对桥梁专家系统存在问题并结合斜拉桥施工控制的特点和要求,阐述了斜拉桥智能施工控制专家系统中推理机制研究的意义。(2)构建了斜拉桥智能施工控制专家系统推理性知识库。采用层次语义网络表示法和知识集成表示法来对知识进行表示,并对斜拉桥施工控制过程中的定性知识进行了量化。(3)构建了斜拉桥智能施工控制专家系统推理机制。推理机制构建主要分为两部分,一是推理机制的推理方式,具体包括演绎推理、归纳推理、默认推理和不确定性推理;二是推理机的控制策略,具体包括正向推理、逆向推理和混合推理。对所选择研究的推理方式和推理控制策略采用示例的方式展开了运用。(4)开发了斜拉桥智能施工控制专家系统推理机制软件。采用Microsoft Visual Studio2010软件作为开发平台,Visual C++作为开发语言,Microsoft ADO.NET作为数据库访问技术。软件应用到如皋长江大桥施工控制过程中,实现了对监测数据的管理、分析评价、控制决策以及异常情况的预警。控制过程及结果表明,达到了理想的推理效果,便于广泛的应用。
[Abstract]:The construction control of cable-stayed bridge is a key technical problem in the construction process of cable-stayed bridge. In this paper, the reasoning mechanism of intelligent construction control expert system for cable-stayed bridge is studied on the basis of the previous research on the expert system of bridge construction control. The main contents of this paper are as follows: (1) the research status of bridge expert system and system reasoning mechanism is analyzed in detail, the existing problems of bridge expert system are summarized, and the structure and organization of intelligent construction control expert system of cable-stayed bridge are analyzed. In view of the existing problems of bridge expert system and the characteristics and requirements of cable-stayed bridge construction control, The significance of reasoning mechanism research in intelligent construction control expert system of cable-stayed bridge is expounded. The reasoning knowledge base of intelligent construction control expert system of cable-stayed bridge is constructed. The hierarchical semantic network representation and the knowledge integration representation are used to express the knowledge, and the qualitative knowledge in the construction control process of cable-stayed bridge is quantified. The reasoning mechanism of intelligent construction control expert system for cable-stayed bridge is constructed. The reasoning mechanism is mainly divided into two parts, one is reasoning mechanism, including deductive reasoning, inductive reasoning, default reasoning and uncertainty reasoning; the other is the control strategy of inference engine, including positive reasoning, Reverse reasoning and mixed reasoning. The reasoning mechanism software of intelligent construction control expert system for cable-stayed bridge is developed by using an example. Microsoft Visual Studio 2010 is used as the development platform and Microsoft ADO.NET is used as the database access technology. The software is applied to the construction control process of Rugao Yangtze River Bridge, which realizes the management of monitoring data, analysis and evaluation, control decision and early warning of abnormal situation. The control process and the results show that the ideal reasoning effect is achieved and it is easy to be widely used.
