摘要
对盾构始发井数字化施工中的测量工作进行了详细介绍.文中在北京地铁十号线十一标段工程中,依据现有控制点和导线点的坐标,将测得的施工场地平面图,输入计算机使整个施工现场数字化,从而形成数字化施工图;并结合传统的一井定向方法来控制反向隧道的施工,有效地提高了测量工作的精度,并大大降低了内业工作量,提高了工作效率.施工完成后,实测误差均能满足隧道贯通精度的要求.
The paper introduces the construction measurement for shield - construction origination shaft in detail. In the No. 11 section of Beijing No. 10 subway, according to the control points and traverse points provided, the construction field horizontal plan was gotten by surveying, and the measure data were put into computer and the digital construction drawing was gained. Then, by using the one - shaft orientation method to control the construction of the reverse tunnel, the accuracy of survey was improved and the quantity of office work was decreased. So, the efficiency was improved. When the construction was completed, the practical breakthrough error reached to the requirement of tunnel engineering.
