摘要
对圆曲线贯通误差进行了深入的探讨。通过坐标变换，求极值及解误差方程等手段，总结出圆曲线隧道贯通在其重要方向上的预计误差为一椭圆，提出了绘制贯通误差椭圆的简明方法，为隧道贯通的设计、施工定位提供了可靠依据。
The error ellipse of joints in circular tunnel is deeply discussed. Through coordinate transformation, seeking for extreme value and solving error equation,etc. it is summed up that the estimated error at the main direction of joints in circular tunnel is an ellipse. A simple method for drawing the error ellipse is put forward, thus providing a reliable basis for design and location under construction of joints in tunnel.
