隧道开挖面轮廓线放样的一种新方法——反演趋近法

A New Method of Cutting Outlines Lay-Out for Tunnel Construction

针对隧道施工的特殊性以及全站仪的三维坐标测量功能 ,结合工程实践 ,提出利用“反演趋近法”进行隧道施工放样的概念和方法 ,可有效提高放样的精度和效率 ,具有一定的推广使用价值。

In view of the specific conditions and the functions of total station's 3 D measuring, the idea of inversed approaching method is used for cutting outlines lay out in tunnel construction, which could improve the accuracy and efficiency and is worth to be widely used.
