Numerical investigation of the correlations of hydraulic and elastic characteristics in diverse carbonate rock types

Deep Underground Science and Engineering, EarlyView.
We use the linear Boolean model and the discrete Fourier transformation approach to generate various carbonate rocks. The lattice Boltzmann method and the finite element method are applied to calculate permeability and elastic wave velocity, respectively.

Investigation of the failure characteristics of fissure tunnels under dynamic and static combinations

Deep Underground Science and Engineering, EarlyView.
This article aims to investigate the dynamic fracture response of fractured tunnel models under zero geological stress through physical experiments and numerical simulations. It further simulates the dynamic fracture characteristics of fractured tunnel models under geological stress ranging from 0 to 2.5 MPa using the numerical software AUTODYN ...

Random finite element analysis on ground subsidence caused by tunnel excavation in karst regions with spatial variable soil

Deep Underground Science and Engineering, EarlyView.
This study investigates ground subsidence during tunnel excavation in karst areas, highlighting the combined effects of karst cave proximity, cave size, and soil spatial variability. Findings suggest that shorter cave distances and larger cave sizes increase subsidence variability, and a modified Peck formula is proposed for more accurate subsidence ...

A rock brittleness index based on the postpeak energy release rate and damage surface characteristics for brittle hard rock

Deep Underground Science and Engineering, EarlyView.
This study examines energy evolution in rock rupture via triaxial direct shear tests, exploring the impact of confining pressure and temperature on fracture surface randomness. A novel energy‐based brittleness index is proposed, validated experimentally, and compared with existing methods for reliability and accuracy.

Environmental and local habitat variables as predictors of trophic interactions in subtidal rocky reefs along the SE Pacific coast

Ecography, EarlyView.
Temperature generally drives latitudinal patterns in the strength of trophic interactions, including consumption rates. However, local community and other environmental conditions might also affect consumption, disrupting latitudinal gradients, which results in complex large‐scale patterns.
