| Abstract: | Model test is a practical method to analysis the mechanical characteristics of lining structure of the large cross-section tunnel.Based on the Longtou mountain tunnel construction in Guangdong province,according to the similar principle of elastic theory,a model test which simulates the destructive power on single-arch large cross-section of bias tunnel is carried out and the failure mechanism of tunnel lining under different surrounding rocks grade is studied.Failure load on the bias tunnel is simulated by... |
