Use of a trench adjacent to a shallow foundation as a mitigation measure for hazards associated with reverse faulting
Evidence from recent earthquakes reminds us that fault-induced permanent ground displacement has a devastating effect on structures in addition to damage caused by wave propagation. Studies have shown that new mitigation measures should be employed to decrease the hazards associated with surface faulting on structures in active fault zones. In this study, the performance of a vertical trench in mitigating the hazards associated with reverse faulting on shallow foundations was investigated using centrifuge model tests. The trench was filled with highly compressible and low shear strength material. The parameters of structural distress, fault-induced rotation and displacement of a shallow foundation were considered when investigating the performance of the trench. The trench was able to significantly decrease the rotation of the foundation and the level of damage to the foundation and superstructure induced by reverse fault rupture. The depth required for the trench in order to divert fault rupture away from the foundation was determined using a simplified analytical model.
