Heating and weakening of faults during earthquake slip
, 2006 [1] Field observations of mature crustal faults suggest that slip in individual events occurs primarily within a thin shear zone,

Deep Underground Science and Engineering, EarlyView.A novel analytical method is proposed to evaluate the shear stress effect on the progressive compressive failure and microcrack growth direction in brittle rocks. The shear stress effect on the wing crack growth direction during the progressive compressive failure is determined. The initial crack angle effect on the y‐direction peak stress and the wing

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.

Nature, 1892 AFTER the Pembroke earthquakes of August 1892, you were good enough to insert a letter from me (vol. xlvi. p. 401) asking for observations from different places. In reply to this letter, I received so many and such valuable records, that I should be greatly obliged if you would allow me to make a similar request for accounts of the recent earthquake of

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.
