Large cyclic stresses induced from heavy traffic can cause significant degradation of rail tracks, leading to poor track geometry and safety. Inclusion of resilient materials such as geosynthetics to reinforce the track substructure has been observed in the ...

Permeability function of an unsaturated soil, k(\), where \ is suction, is a vital hydrogeological property that governs seepage in various geotechnical problems. Owing to considerably long test duration, direct measurement of k(\) is often avoided if at all ...

In this study swelling problem caused by claystone containing smectite group clay mineral in Tire Lignite Enterprise (Izmir, Turkey) was investigated and triaxial swelling behavior of the claystone was determined.

In this study are developed and presented results from a time-forward three-dimensional (3-D) model of the San Andreas fault system near its Big Bend in southern California.

This paper provides a review of hydromechanical (HM) couplings in fractured rock, with special emphasis on HM interactions as a result of or directly connected with human activities.

The San Andreas fault in California has long been thought to be far weaker than given by the Anderson-Byerlee state because of the lack of a heat-flow anomaly adjacent to the fault as predicted by a steady-state conductive model of frictional heating. Here ...

The history of stress around a circular tunnel during excavation in a homogeneous, isotropic, linear elastic or plastic medium with a strain softening behavior, subjected to either isotropic (Ko = 1) or anisotropic (Ko = 2) state of stress, in 3D conditions ...

To provide a better understanding of the mechanics of strata deformation, the authors have collected and reviewed measurements of convergence and stress in one western U.S. mine and have completed pseudo-three-dimensional, boundary-element modeling for two ...

The U.S. Bureau of Mines is investigating longwall panel layouts to maximize coal recovery and minimize interactive problems in multiple-seam operations. When coalbeds are longwall-mined in descending order, the transfer of stress from overlying gate roads ...

An analysis is presented of the accumulation of stress along the North Anatolian fault.The analysis is based on the time-dependent reloading of the plate boundary by using a modified Elsasser model of a coupled lithosphere-asthenosphere system.
