邯长高速公路中的坐标系转换

Coordinates Transformation in Handan-Changzhi Freeway

在公路工程施工中,当路线较长或地形起伏较大时,常遇到复测导线边长与设计提供的结果不符的情况。而长距离的线路勘测工程中不可避免地会出现多个坐标系,这也给设计和施工带来诸多不便。因此应建立一套适宜该类工程特点的坐标系理论及实施方法。

When the route is longer or the landform undulation is quite big, there are many situanons that the results measuring are not in accordance with the design provided in the highway construction. Because there are many coordinates system in the long route engineering, which bring a lot of inconveniences for design and construction. We should establish theories and method of coordinates transformation suitable for this type of engineering characteristics.
