曲线贯通误差预算方法探讨

The Study of Curve Tunnel Error Estimation Method

本文介绍一种曲线隧道贯通误差预计的新方法。该方法通过求导线误差重心,坐标变换和分离的手段对原方法作了重大的改进,从而使计算变得简单。

This paper introduces a new method that estimates the through error of a curve tunnel. The method is greatly improved on an old one by calculating traverse error orthocenter, coordinate transformation and separation. so as to make the calculation easier.
