Numerical modeling of the interaction of normal fault and shallow embedded foundation

The consequences to structures caused by permanent fault displacement have been investigated for dip-slip faulting, but not the effect of embedment depth on interaction between a normal rupture and shallow embedded foundation. This study foundation using numerical model validated with centrifuge experiments. It was found that gapping mechanism distress occurred at different positions relative outcrop an in comparison surface extent this area depended combined influences position, surcharge, depth, dip angle. sidewalls were observed act as kinematic constraints had considerable influence rotation, stressing foundations. With regard level rotation foundation, lateral earth pressure distribution footwall sidewall similar Rankine active triangular hangingwall parabolic passive pressure. Foundations laid loose soil exhibited less than those dense because ruptures absorbed or bifurcated around both sides
