精密导线测定拱型建筑物水平位移的精度分析

Precision Analysis on Horizontal Displacement of Arched Structures in Precise Traversing

讨论拱型建筑物变形监测中精密无定向导线和测定向角的精密导线的精度,并以实例分别绘出了这两种导线的点位误差椭圆和边方位角误差分布图.据此得出了几点有益的结论和建议.

The article mainly discusses astatic precise traversing and measured precise traversing in monitoring deformation of arched structures. The two traverses-error ellipses in point measurement and error distribution of side position angles-are illustrated respectively. A few helpful conclusions are drawn accordingly.
