A Computer Aided Monitoring Network Design System (CAMNDS)

本文系统讨论了评定工程控制网质量的精度、可靠性和灵敏度指标,提出变形监测网应以灵敏度作为衡量监测网的主要质量准则,针对具体的变形模型建立了主要以灵敏度、可靠性及费用等为质量准则的机助优化设计系统CAMNDS,并用灵敏度敏感元素作为修改设计的主要依据,具有机助——解析法的特点。该系统还可用于一般工程控制网优化设计。最后,本文给出了某工程监测网优化设计的实例。

In this paper, the aspects of accuracy, reliability and sensitivity of an engineering control network are systematically disscussed. It is proposed that a monitoring network should take the sensitivity as the pricipal quality criterion in network design.With a specified deformation model, a computer aided monitoring network design system(CAMNDS)concerning the quality criteria of sensitivty, reliability and economy is developed. In the system, the main judgement for modifying the design is the sensitive elements. Therefore it has both analytic nature and computer aided simulation nature. The system can also be used in the design of general engineering control network. Finally a typical example is given using the system and some useful conclusion are drawn.
