A microseismic source location method considering diffraction used in tunnel engineering
In order to improve the accuracy of rockburst warning, it is necessary to accurately interpret the microseismic (MS) information obtained during the rockburst development process. However, the MS source locati...

Deep learning based water leakage detection for shield tunnel lining
Shield tunnel lining is prone to water leakage, which may further bring about corrosion and structural damage to the walls, potentially leading to dangerous accidents. To avoid tedious and inefficient manual i...

Estimating the complete in-situ stress tensor along deep tunnels with frequent rockbursts near a steep valley
The intensities and locations of rockbursts directly relate to both the magnitude and direction of the in-situ principal stresses in the rock mass. Therefore, achieving an accurate estimation of the in-situ stres...

Failure Modes of Jointed Granite Subjected to Weak Dynamic Disturbance Under True-Triaxial Compression
Most rockbursts are associated with jointed rock masses as the energy stored inside the rock is prone to abruptly release at such discontinuities. Moreover, remote blasting at working faces can trigger the bri...

Brittle failure modes of underground powerhouses: an insight based on true triaxial compression tests
The directions of in situ principal stresses and curvature of the opening boundary play a major role in determining the failure modes of underground powerhouses. Considering the major in situ principal stress σ1 ...

Ground load on tunnels built using new Austrian tunneling method: study of a tunnel passing through highly weathered sandstone
The ground load acting on a tunnel is an important issue in tunnel design, especially when the tunnel passes through highly weathered sandstone. A systematic field-monitoring campaign was performed to investig...
