特长隧洞精密测量导线网的控制

Control of Precision Measurement of Traverse Network in Specified Tunnel

隧洞内控制测量精度的高低就直接影响到贯通的精度,为保证隧洞在允许精度内贯通,尤其是在小断面,大坡度,小边长,小角度的隧洞中,我们首先要对洞内控制测量进行设计,如何布置测量导线网,采用何种方法进行导线测量尤为重要。

The level of control measurement accuracy in the tunnel directly affects the accuracy of the penetration. In order to ensure that the tunnel runs through the allowed accuracy, especially in tunnels with small sections, large slopes, small edges, and small angles, we should firstly design the control measurement in the hole. How to arrange the wire network, and which method is used to do the wire measurement is particularly important.
