摘要
在交通工程的隧道和矿山井下建设中,由于预计贯通平面测量误差的传统图解法存在缺陷,提出用误差椭圆和坐标变换2种解析法来预计贯通测量平面误差,并通过实例证明,这2种新方法过程简单,不仅可以提高平面贯通测量的精度,还可以节省时间,提高工作效率。
In the construction of tunnels of the traffic engineering and underground mines, because of the inadequacy of the traditional graphical method expected to run through of plane measurement error, the two types of analysis： the error ellipse and coordinate transformation met p areis expected to work out error, and it has proved that two new method is simple, not only can improve the precision of the plane error, but also can save time and enhance efficiency by example.
