高速公路恢复中线的坐标放线法

The LSC for the restoration of center line during highway construction

高速公路施工过程中。中线恢复至关重要。本文介绍了一种与传统方法相比具有快速、准确、方便,而且不易受障碍物影响、无丈量累积误差的坐标放线法。并重点阐述了坐标放线法的原理。坐标计算的方法及发展前景。

The restoration of centre line during highway construction is very important. The authors introduce a USC location method which is quick, accurate and convenient comparing with traditional method. This method is not easy to be affected by obstructions and has no measuring accumulative errors. The authors state the principle of USC location method and its calculation and prospectivity.
