EXPERIMENTAL VALIDATION OF A NUMERICAL MODEL: REVERSE FAULT RUPTURE PROPAGATION THROUGH SAND

概要

論文の詳細を見る
In this study, a sophisticated numerical model incorporating a hardening-softening constitutive model with shear band is calibrated from the direct shear test results, and validated for the prediction of the behaviour of medium dense Fotainebleau sand bed for quasi-static displacement induced by reverse fault's base rock with dip angle of 60°. The vertical displacements profile of the ground surface, minimum vertical base displacement for the rupture to reach the ground, the average dip angle propagated into the soil as well as the horizontal extent of the deformed surface ground due to different stress fields (centrifuge and 1g tests) are evaluated by having close agreement between experiments and numerical analyses.
