摘要
针对工程测量中边长变形的问题,介绍了通过选择或建立合适的坐标系统来控制边长变形的方法;论述了国家统一的高斯平面直角坐标可能给工程施工带来的影响以及国家统一的3°带高斯平面直角坐标系与独立的施工坐标系之间的转换关系。
To solve the problem of length deformation in engineering survey,this paper has introduced several methods of controlling length deformation by choosing and setting up the suitable coordinate system, and has described the influence of rectangular coordinate system of Gaussian plane on project construction and the convertible relation between rectangular coordinate system of Gaussian plane according to 3 degrees zoning on the surface of referenee ellipsoid and independent coordinate system for constructions.
