Optimization of rock bolt support parameters for TBM tunnels in high in situ stress soft rock based on deformation and stress evolution analysis

Large deformation of surrounding rock is a critical challenge during TBM tunnelling in deeply buried high in situ stress soft rock, where delayed deformation and insufficient support stiffness may lead to support failure and machine jamming. However, the quantitative influence of rock bolt support parameters on def...

Numerical Study of Failure Mechanism and Effectiveness of Control Measure of Soft Rock Roadways Affected by Humidity Diffusion

Understanding the failure mechanism of soft rock roadways in high-humidity environments, as well as designing appropriate control measures, are critical for ensuring their stability. In this study, swelling and triaxial compression tests on argillaceous sandstone were first performed. Results show that the triaxial com...

Experimental and Numerical Study of Water Effects on Mechanical and Fracture Behavior of Sandstone: A Case Study

Water significantly modifies rock mechanical performance and fracture characteristics through water content and water distribution. Nevertheless, the evolution laws of rock mechanical properties and underlying fracture mechanisms under variable water conditions remain incompletely clarified. In this study, uniaxial com...
