摘要
在监测网设计阶段,不仅要考虑不同变形模型之间的可区分度,而且要研究变形与粗差的可区分度,即双可区分度,以利以后进行变形分析。文中导出了变形与粗差的可区分度,并以双可区分度为准则进行监测网非线性动态优化设计。同时给出了一个非线性直接优化算法,该算法避开了常规的台劳级数线性展开的方法,易于在计算机上实现。
This paper discusses that we should take into account not only the separability among various deformation models, but also the separability between the deformation and gross errors, that is double-separability, in the design of deformation monitoring networks. This will benefit to the of deformation. Separability of deformation and gross errors has been derived by the author. The double-separability is used in the nonlinear-dynamic optimization design of deformation monitoring networks. A nonlinear direct optimization algorithm is given. The algorithm is diferent from the Talor expansion methods and easy to be realized by computer.
