Stability evaluation of deep-buried TBM construction tunnel based on microseismic monitoring technology

Tunnelling and Underground Space Technology, 2018
Abstract During the construction of Duoxiongla tunnel in Tibet, China, instabilities of the surrounding rock such as rock spalling, rock collapses and rockbursts frequently occurred. An advanced microseismic (MS) monitoring system was built to monitor and evaluate the stability of the rock masses under tunnel boring machine (TBM) excavation.

Study on Wall Rock Pressure Equations of Deep-Buried and Large-Span Tunnel

Applied Mechanics and Materials, 2011
Theory equations and specification equations are currently main methods to calculate wall rock pressure. These equations are created in certain backgrounds, and are applicable in certain ranges, not fit for deep-buried or large span tunnels. Analysis methods combined with actual project are used, and measured data are contrasted with the theoretical ...

Numerical Investigation into Rockburst Proneness of Deep-Buried Tunnels with Arch-Shaped Wall

Advanced Materials Research, 2011
During the construction of the deep-buried tunnels, high surrounding rock stress and the rockburst are the important factors affecting the stability of surrounding rock. Xiabandi hydraulic engineering is the key project in Tarim River basin. Due to the deep buried excavation, rockburst is particularly prominent and should be received adequate attention.

Back Analysis of Initial Stress and Mechanical Parameters in Deep Buried Highway Tunnel

Advanced Materials Research, 2011
The in-situ stress is one of important basic data for stability evaluation, engineering design and construction of tunnels. For southwest high mountain region, the in-situ stress in the site test is very difficult. Thus, for satisfying engineering design and construction, it is necessary to back analyze the in-situ stress.
