An Explicit Numerical Manifold Method and Its Application on Modelling Tunnel Failure Process
Abstract: The failure of tunnel can affect personal safety and even result in great economic loss. Investigating the failure process of tunnel is one of the key issues of rock mechanics. In this study, the failure process of a deep buried rock tunnel is numerically investigated by the numerical manifold method. An explicit numerical manifold method (ENMM) based on the Newmark time integration method is...

Evaluation of Tunnel Lining Structures Built in Expansive Rocks Considering Ground Water Effect
Abstract: The construction of tunnels excavated in expansive and water-rich rocks involves significant concerns for the safety of lining structures. This paper focuses on an ongoing tunnel excavated in silty mudstone within water-rich strata. Laboratory mechanical test and mineral composition analysis are conducted to investigate the expansive characteristics of rocks. It is analysed that the rocks...

Methodology and analysis for the automatic tunnel deformation detection based on 3D LiDAR point cloud
Abstract: The tunnel deformation monitoring methodology based on 3D LiDAR (Light Detection and Ranging) data shows broad application prospects in recent years due to the high- quality of acquired massive data. The proposed methodology provides a clear processing flow and comprehensive analysis result with adequate accuracy mainly by three parts: data acquisition, data processing and result analysis....
