空间距离交会在大坝水平变形监测中的可行性分析

Feasibility Analyses of Linear Intersection Usage in Deformation Measurement of Dam Horizontal Removal

基于空间距离三维交会的数学模型 ,提出针对太河水库大坝水平位移变形监测工作基点进行无角度观测方案 ,并对监测的精度进行了预计分析 ,证明此方案不仅经济快捷且合理可行 ,同时也证明空间距离交会定位取代传统量边、测角定位的可行性 .

On the basis of linear intersection in space,a surveying method of work base points in horizontal removal deformation measurement of Taihe dam is discussed.This paper analyses the processing and the observing precision,and illustrates the method is efficient and usable.
