摘要
本文根据新奥法隧道施工中位移监测的特点 ,结合现代测量仪器的发展 ,探索了两种隧道位移监测的新方法 :三维位移监测系统和隧道周边收敛的自由测站监测系统。其中 ,前者可以及时、快速、精确地在一个测站为多个监测断面提供可靠的三维变形量 ;后者可以大致在同一个测站上 ,以足够的精度为多个监测断面提供隧道周边收敛信息 ,其工效能比传统方法成倍提高。
In this paper, according to the trait of displacement monitor of NATM and combined with the develop of modern instrument of measure, two new methods of diplacement monitor of tunnel are put forward: “the system of three dimensional displacement monitor” and “the arbitrary point system of peripheral convergence of tunnel”. The former, at one point, can provide the dependable informations of three dimensional deformation for several sections of inspect in a short time. The latter, can provide the accurate informations of peripheral convergence of tunnel for several sections of inspect, and its working efficency can be improved distinctly than the conventional method.
