摘要

分岔隧道是一种新型结构形式的隧道。以八字岭分岔隧道为工程背景，首先介绍了分岔隧道现场变形监测方法；接着分析了在当前支护和施工方案条件下隧道纵向变形特点、大拱段伴随开挖和支护进行表现出来的施工动态响应特点及隧道开挖面表现出来的空间效应特点。最后，在分析隧道变形特点的基础上，给出了相应的施工对策。研究结果为分岔隧道的设计、施工提供了必要的依据。

Abstract

Bifurcation tunnel is one of the new types tunnels. With less unitary cost for joint bridge-tunnel projects

it is promising in communications construction in West China. A case study of Baziling diverging tunnel is given. The deformation monitoring system is described. The deformation characteristics under the given lining system and construction technology are analyzed. They are longitudinal deformation of the tunnel

construction response of single-arched segment and the influence of the interaction between the two working face. Finally

based on the deformation characteristics

the countermeasures of construction technologies are given. The study provides indispensable evidence for the design and construction of the bifurcation tunnel.
