| 摘 要： | 在公路控制测量的平差计算中,须将外业观测值化算为参考椭球面上的观测值,然后再化算为高斯平面上的观测值,并在高斯平面上进行控制网的平差计算.在这个复杂的数据处理过程中,不可避免地会产生边长投影变形.为此,提出了公路测量坐标计算方法.经工程实践证明,该法可基本消除前述的边长投影变形,且理论简单,方法可行.

| Abstract: | In adjustment calculation of highway control survey, field observation values must be changed onto reference ellipsoid and then onto Gauss projection plane, at last the control network would be adjusted in this plane. In the complicated data disposal course, projection deformation of lengths is ineluctability to take place. For reason, author puts forward coordinate calculation method of highway survey. The method is proved by practice to enable to basically dispel deformation of side-lengths mentioned above, and the theory is simple and the method is feasible. |
