Genesis and reservoir preservation mechanism of 10 000‐m ultradeep dolomite in Chinese craton basin

Deep Underground Science and Engineering, EarlyView.
Potential exploration target stratum of 10 000‐m ultradeep dolomite in Sichuan Basin and Tarim Basin, China. Abstract The 10 000‐m ultradeep dolomite reservoir holds significant potential as a successor field for future oil and gas exploration in China's marine craton basin.

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 ...

Ground vibration isolation using mass scatters: A comparative study with trench barriers and wave‐impeding blocks

Deep Underground Science and Engineering, EarlyView.
Ground‐borne vibrations are a frequent source of environmental problems. A full‐scale experiment is conducted to validate a 3D numerical model in order to analyze the efficiency of three methods of isolation. Trench barriers and wave‐impeding blocks are impractical and expensive methods of isolation, but mass scatters appear to be an efficient ...
