摘要
Abstract
The issues of stability control of the newly-built Pingfengling Tunnel adjacent to the existing Pingfengling Tunnel were analyzed by means of numerical simulation, in terms of the rock pillar’s reserving between the two tunnels, the construction method for the newly-built one, the support forms and so on. As a result, an integrative control measure of tunnel stability has been proposed, such as reserving 8 m rock pillar, using single side drift method, and using advanced small ducts to laterally strengthen in 45°direction of tunnel axis.关键词
