1) Reinforcement in middle rock pillar
中夹岩柱加固
2) middle rock wall consolidation technology
中岩柱加固
1.
Neighborhood tunnel is a special tunnel structural style different from multi-arch tunnel and separated tunnel,and the construction methods and middle rock wall consolidation technology are still in developing stage.
小净距隧道是有别于连拱隧道和分离式隧道的一种特殊的隧道结构形式,其施工方法和中岩柱加固技术还处于研究发展阶段。
3) middle pillar reinforcement
中间岩柱加固
1.
By combining the theoretical analysis and computer simulation technology,and coMParing the arch-top settlement,surface subsidence and middle rock pillar displacement of a large section shallow neighborhood tunnel under the condition of class Ⅴand class Ⅳ,the method of middle pillar reinforcement was analyzed in this paper.
采用理论分析模型与计算机数值模拟相结合技术,对Ⅴ、Ⅳ类围岩条件下的大断面小净距隧道进行隧道拱顶下沉、地表沉降、中间岩柱位移及围岩稳定性的对比,分析中间岩柱加固方法,为工程设计和施工提供参考和指导。
5) inter-space rock
中夹岩层
6) middle-rock wall
中夹岩墙
1.
For small clear space tunnel,because the width of middle-rock wall is as small as 5 to 7 m,the loosening zone of two tunnels could be overlaid during the process of construction which results a large vertical displacement of middle-rock wall and leads to the augment of span of slumping arch and stress raising of th.
塌落拱的高度一般在3~4m(隧道宽度15m),小净距隧道中夹岩墙宽度只有5~7m,在施工过程中,2个隧道的松动圈会出现重叠,使中夹岩墙产生较大的垂直向下位移,从而增加了塌落拱的跨度,中夹岩墙上部的应力相应增加。
