摘要
迄今,国内外对变形监测的优化设计大都局限于静态网模型的研究,而且是采用单目标函数优化模型。变形监测网在空间和时间上都是变化的,显然采用顾及地表运动的动态优化设计模型设计观测方案才是科学的、准确的。本文首次提出了同时考虑变形参数精度、变形观测工作量或观测费用和变形监测可靠性三项准则的双目标函数动态优化设计模型,可设计一个变形参数精度高、观测费用低、具有一定可靠性的变形观测方案。
Up to now,study of optimization of deformation monitoring at home and abroad is carried out only by use of static models of single object function.Because a monitoring network changes in space and time,it is reasonable and accurate to apply dynamic optimal models in design of observation plan,which considers earth movement.This paper presents for the first time a method to establish dynamic models by use of double object functions,which gives consideration of accuracy of deformation parameters,the amount of work or costs,and reliability. It will produce a plan with high accuracy,low cost and high reliability.
