隧道控制测量的主要目的是保证隧道在多个开挖面的相向施工中,使其中线符合路线平面和纵断面的设计要求,在允许误差的范围内,在满足限界要求的条件下正确贯通。本文结合卧龙沟1#隧道的测量谈谈小半径螺旋隧道的测量控制技术。
The main purpose of tunnel control measurement is to ensure that the tunnels meet the design requirements of the route plane and longitudinal section in the construction of multiple excavation faces in opposite directions and correctly penetrate within the allowable error range and meet the requirements of the boundary clearance. In this paper, Wolong ditch 1 # tunnel measurement measurements talk about small radius spiral tunnel measurement and control technology.
