| 摘 要： | 本文通过模型试验,对均匀、连续的软弱围岩中开挖的深埋隧道,在初始主应力比一定(N=O.5),但方向(a)变化条件下洞室剪切破坏的形态及其位置、锚杆布置及其受力与围岩变形的关系、锚杆的支护作用进行了试验研究。对典型的主应力偏离条件下的隧道,分别提出了一个较为合理的锚杆支护形式,以供在预设计参考。

| Abstract: | Experimental research and FEM calculations have been carried
out on the state and distribution of tunnel shearing failures,
and on the pattern of rock bolt and its strengthening effects
under different conditions of initial stress direction during tunnel
excavation in homogeneous,continuous,isotropic soft grounds.
More reasonable types of rock bolt support have been offered
for typical tunnels under different dit directions of main stress.
The results can be used as reference in tunnel design. |
