摘要
高速公路平面控制测量需要将控制点纳入国家高斯平面坐标系,由此不可避免地出现距离长度变形,并导致平面控制测量投影面与施工高程面分离。通过分析长度变形产生的原因、国家统一坐标系的局限性以及长度变形对路线测设误差的影响,提出了减小长度变形对高速公路施工精度影响的方法。
It is inevitable that the length distortion will happen when the control points are linked to the State Gauss Plane Coordinates System in the plane control surveying for speedways,by which the construction elevation plane would separated from the projection plane of control surveying.Hence,a new method is proposed to lessen the affection of length distortion in speedways' construction by means of some analysis on the causes of the distortion,the limitation of state coordinates and the affection of length distortion on the route laying-out error.
