摘要
在隧道施工中如何对超欠挖进行有效控制,一直是值得探讨的问题。用坐标法精确放样隧道开挖轮廓线的算法,通过对计算原理、计算步骤进行详细讲解,并结合实例进行分析计算,对各种类型的隧道施工放样计算具有一定的指导意义。
It is worthy to discuss how to carry out effective control in tunnel construction. With the coordinate method and the precise lofting algorithm to excavate the tunnel＇s contour line, this article explains in detail the calculating principle and procedures, and analyzes the concrete examples, so it can be referred to in different types＇ tunnels＇ construction lofting algorithm.
