| Abstract: | In accordance with the features of the uneven pressure caused by geologically bedding strata acting on Yutangwan tunnel on Chongqing ~ Huaihua railway line,an experimental study on the uneven rock pressure applied on the lining structure of tunnel models was carried out based on the theory of analogy.The distribution of rock pressure applied on the tunnel and the relation between the pressure and the inclination angle of bedding strata were revealed.The structural configuration of tunnels embedded in geologically bedding strata and the corresponding supporting approaches were also discussed in the paper. |
