摘要
实际工程建设中,为满足投影长度变形要求,通过选择恰当的中央子午线和高程投影面来建立工程独立坐标系,保证工程顺利实施。本文以新疆某线路工程为例,探讨了工程独立坐标系的建立方法极其优缺点,可为类似工程提供借鉴。
In order to meet the requirements of projection length deformation in the actual project construction,the independent coordinate system of the project is established by selecting appropriate central meridian and elevation projection plane to ensure the smooth implementation of the project. Taking an expressway project in Xinjiang as an example,this paper discusses the advantages and disadvantages of the establishment method of engineering independent coordinate system,and provides reference for similar projects.
