摘要
该文结合轨道交通2号线东延伸段工程(机场段)施工控制测量的案例,阐述在投影带的边缘高斯投影改化值比较大且工程精度要求也比较高的情况下,如何进行测距边长改化的方法,并通过实例计算进行精度测评。
Combined with the construction control measuring case of Rail Traffic No.2 Line East Extension Project (Airport Section), the article sets forth how to carry out the measuring distance side length correction method under the condition that the edge Gauss projection correcting value of the projection belt is larger and the engineering precision requirement is also higher, and carries out the precision measuring evaluation by the calculation of the practical example.
