Gas migration at the granite–bentonite interface under semirigid boundary conditions in the context of high‐level radioactive waste disposal

Deep Underground Science and Engineering, EarlyView.
A series of water infiltration tests and gas permeability tests were conducted on granite and granite–bentonite samples. According to the results, the interfaces between granite and bentonite and the damaged granite were considered to be the preferentcial pathway for gas migration.

Analysis of squeezing‐induced failure in a water tunnel and measure of rehabilitation: A case study of Tishreen tunnel, Syria

Deep Underground Science and Engineering, EarlyView.
Different failure modes observed in Tishreen tunnel include Floor heave, wall spalling, crashing of slab, and lining convergence reaching the failure limit. Abstract Squeezing phenomena can lead to severe loads in deep tunnels, especially in the presence of a low ratio of surrounding rock strength to overburden pressure.

A review of multiscale numerical modeling of rock mechanics and rock engineering

Deep Underground Science and Engineering, EarlyView.
Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...
