Abstract Abstract：Research purposes： Affected by the terrain and engineering geological environmental conditions, the relative stability of the surrounding rock in the portal section of tunnel engineering is poorer, the construction difficulty and the risk is bigger, the way of design and construction of entrance from the outside to the inside is generally used, and there is little information about the design of exit from the inside to the outside. This paper combined with specific engineering case for the design of tunnel engineering in the research, better realized the tunnel engineering of exit tunnel construction, put forward the design method of exit tunnel, and summarized its advantages and application promotion value,to provide the reference for the designer and constructor.
Research conclusions：(1) The design of exit tunnel need to study the hole location and tunnel portal design, construction scheme, structural design, aided engineering measures, hole slope treatment, etc.(2) Application in the engineering example, verifies that the design scheme of exit tunnel is feasible and reliable, and achieves good social and economic benefits. (3) This paper also summarizes its advantages and application promotion value of exit tunnel, especially suitable for medium and short tunnel or one end into the tunnel hole construction.
