带状工程测设长度变形控制的研究

摘要

According to the features of the measured length deformation in the belt projects,the paper researches the identification methods for the controlled length deformation and the compensating protection plane to make the maximal deformation of all points at the measured area be minimal,and points out the distribution law of the deformation error should be considered in the selection of the compensating protection plane.%根据带状工程测设长度变形的特点,通过对控制长度变形和抵偿投影面确定方法的研究,使测区内所有点的变形最大值达到最小,并提出了＂抵偿投影面＂的选取应考虑变形误差的分布规律。
