Collapse risk assessment of deep-buried tunnel during construction and its application

Tunnelling and Underground Space Technology, 2021
Abstract The hazard of tunnel collapse is a key factor restricting the excavation progress and safety of the tunnels excavated by drilling and blasting. To control this construction risk, a new risk assessment method of tunnel collapse involving case analysis, advanced geological prediction, and Dempster-Shafer (D-S) evidence theory is put forward ...

Support pressure assessment for deep buried railway tunnels using BQ-index

Journal of Central South University, 2021
Estimation of support pressure is extremely important to the support system design and the construction safety of tunnels. At present, there are many methods for the estimation of support pressure based on different rock mass classification systems, such as Q system, GSI system and RMR system. However, various rock mass classification systems are based

Transverse extent of numerical model for deep buried tunnel excavation

Tunnelling and Underground Space Technology, 2019
Abstract Numerical simulation has been widely used for predicting rock mass convergence during tunnel excavation. Considering that tunnel construction is a three-dimensional (3D) process, the 3D numerical analysis, instead of the plane-strain models, are commonly employed in engineering practice.
