三种基于免棱镜技术圆筒构筑物倾斜观测方法

Three Inclination Observation Methods for Cylinder Structure Based on Three Measurements without Prism

为了提高圆筒构筑物倾斜观测效率,结合工程实例分析比较了三种基于免棱镜全站仪的监测方法。结果表明:"同高点"曲线拟合精度高,"测边网"迭代平差解算可得相似成果;圆柱偏心测量方法简捷、精度满足安全监测要求;筒壁点阵数据绘成的倾斜等值线图,能较好反映筒壁整体变形。

In order to improve the efficiency of inclination observation for cylinder construction,the paper compares three monitoring methods based on total stations without prism.The results show that "the same height point" has higher curve fitting accuracy,"atrilateration network" adjustment calculation has the similar results,cylinder eccentricity measurement method which can meet the de security demand is much easier,and inclination contour of lattice data of cylinder wall is able to reflect the deformation better.
