Forward prediction for tunnel geology and classification of surrounding rock based on seismic wave velocity layered tomography

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2023
Excavation under complex geological conditions requires effective and accurate geological forward-prospecting to detect the unfavorable geological structure and estimate the classification of surrounding rock in front of the tunnel face.

Inverse modelling in geology by interactive evolutionary computation [PDF]

open access: yesJournal of Structural Geology, 2003
Inverse modelling of geological processes, in the absence of established numerical criteria to act as inversion targets, requires an approach that uses human interaction to assess forward model results. The method of interactive evolutionary computation provides for the inclusion of qualitative geological expertise within a rigorous mathematical ...

Analogue Modelling of Inverted Oblique Rift Systems [PDF]

open access: yes, 2005
The geometric evolution of brittle fault systems in inverted oblique and offset rift systems has been simulated using scaled sandbox analogue models. Dry fine-grained quartz sand was used to represent the brittle upper crust.
