2) inter-space rock
中夹岩层
3) 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。
4) Sandwiched rock
中间夹岩
1.
Sandwiched rock between twin closely spaced tunnels is in complicated and three-dimensional stress state.
小净距隧道的中间夹岩处于复杂的三维受力状态。
5) intermediate rock
中性岩;夹层
6) Reinforcement in middle rock pillar
中夹岩柱加固
