Centrifuge modelling of normal fault–foundation interaction

摘要: Earthquake fault ruptures may emerge at the ground surface causing large differential movements. When or adjacent to position of existing foundations, significant damage can be caused. However, study recent faulting events revealed that in some circumstances fault-rupture emergence is deflected by presence buildings leaving intact. A centrifuge modelling has been conducted investigate how normal faults interact with strip foundations which run parallel strike direction. The confirms rupture deviated foundation so protected from most serious whilst propagates soil withstand initial movements before final mechanism activated. results suggest it bearing pressure causes deviation rather than kinematic restraint foundation. interaction between earthquake and shallow depends on pressure, width, depth relative these aspects should considered design. Results tests are used validate a series finite element analyses as reported an accompanying paper.
