A Study of the Mechanical Properties of Middle-Rock-Wall and Preliminary Lining of a Shallow Large-Span Tunnel with Small Interval
Publisher: American Society of Civil Engineers
Abstract: Mechanical properties such as stress, deformation, and plastic zone distribution of the middle-rock-wall, along with the mechanical characteristics of the preliminary lining under different spacings, are particularly ...
Refinement Identification and Evaluation of Tunnel Lining Cracks
Publisher: ASCE
Abstract: In order to study the precise description and feature quantification of the tunnel lining crack morphology, the paper uses the tunnel lining panoramic-image method to rely on the Wujing Expressway Qingyantou Tunnel as the ...
Analysis for Microseismic Energy of Immediate Rockbursts in Deep Tunnels with Different Excavation Methods
Publisher: American Society of Civil Engineers
Abstract: This study integrates microseismic data and data from hundreds of rockbursts of different intensities that occurred in a water drainage tunnel and four deep headrace tunnels at Jinping II Hydropower Station in Sichuan ...
