对施工单位而言,洞内控制测量精度的高低就直接影响到贯通的精度。保证隧洞在允许精度内贯通,首先要对洞内控制测量进行设计,在未贯通前对已施测的测量成果要进行相应的精度估算,为保证相应的控制测量精度还要采取相应的测量方案。探索隧洞洞内工程的控制测量设计、精度估算的测量方法,从而保证相应的控制测量精度。
The construction unit, the level of control accuracy of the hole directly affects the penetration accuracy. To ensure that the tunnel penetrates within the allowable accuracy, we must first design the control measurement inside the hole, before the measurement of the measured results have to be carried out to estimate the appropriate accuracy, in order to ensure the appropriate control measurement accuracy but also to take the appropriate measurement programs . Explore the tunnel tunnel engineering control measurement design, accuracy estimation of measurement methods, so as to ensure the appropriate control of measurement accuracy.
