三维变形监测网的优化设计

在变形监测中，采用布设三维网，避免将空间置问题分成二维平面和一维高程单独处理带来的缺陷，从而可更严密地获得监测点的空间关系，使变形分析结果更符合客观实际。本文针对三维变形测网的布设，提出了两个方面的优化设计模型，设计观测精度，本模型可设计一个精度高、观测费用低、具有一定可靠性的变形监测方案。

Optimun Design of Three-Dimensional Deformation Monitoring Networks

ln design of deformation monitoring networks,three-dimensional networks Can avoid the defect which is caused by dealing with the problem of the space position through dividing it into two-dimensional plane surveying and one-dimensional height one,and can obtain the spatial relations of monitoring points more strictly sp that the result of analysis of deformation conforms to the objective reality. This paper presents models about two aspeets including design of observation scheme and the choice of observation precision.These models can be used to design the deformation monitoring scheme with high observation Drecision,low coit and definife reliabilitv.
