摘要 本文将测边建筑方格网模拟成平面桁架结构,运用有限单元理论,结合测边建筑方格网和桁架结构自身的特点,提出了一种解该网平差问题的新方法. In this artical, the linear measurement building rectangular network is imitated to the truss frame structure of plane.By applying finite element theory and combining the features of the linear measurement building rectangular network and the truss frame structure, a new method for solving the problem of adjustment of the linear measurement building rectangular network is proposed.
