The nonlinearity of rock becomes more significant as the buried depth increases, which
changes the stress redistribution and deformation patterns during tunneling. In this study, a …

With the rapid development of the tunnel project, the problem of soft rock tunnel support has
become increasingly prominent. The prestressed anchor support method has made great …

Deep soft rock roadways generally present large deformation characteristics, and a vast
number of workers attempt to repair them to no avail. A true 3D model test was performed …

Tunnels are unavoidably constructed in layered rock masses, and tunnel collapses are often
associated with such layering. Two violent collapses at the Yangshan tunnel were analysed …

The deformation and failure of deep soft rock roadways become more prominent. In this
paper, two true triaxial model tests were carried out to investigate the deformation and failure …

With the increase in mining depth and the deterioration of surrounding rock conditions, large
deformation failure of deep roadway surrounding rock is still very common. To solve the …

This paper studies the creep deformation and failure characteristics of a soft rock roadway
under the condition of combined support through a model test that lasted for 30 days. Under …

For tunneling in a deep, soft rock mass, rock deformation and lining pressure, which are time-
dependent behaviors, are mainly affected by rock rheology and longitudinal excavation …

With the increase of burial depth, complex geological environments such as high in-situ
stress and high seepage pressure will inevitably affect the generation of zonal disintegration …

In order to systematically evaluate the damage degree in Jinping deep tunnels during
excavation, an improved SPH algorithm with good Lagrangian characteristics is introduced …
