Dip-Slip Faulting
Recent earthquakes, such as Kocaeli (Turkey 1999), Chi-Chi (Taiwan 1999), Wenchuan (China 2008), Kaikoura (NZ 2016) and Kumamoto (Japan 2016) have shown that faulting-induced deformation can cause substantial damage to infrastructure. Until recently, little field evidence was available on the interaction of foundations and structures with a surface fault rupture. Starting with field studies after the 1999 Kocaeli and Chi-Chi earthquakes (external pageJ7, external pageJ8, external pageJ14), we have been studying Fault Rupture–Soil-Foundation-Structure Interaction (FR–SFSI) combining physical and numerical modelling.
After developing and validating our numerical methods through blind Class “A” predictions of centrifuge model tests (external pageJ5, external pageJ15), we investigated the response of a variety of foundations subjected to dip-slip (normal and reverse) faulting, including shallow strip foundations (external pageJ18, external pageJ20), caisson and piled foundations (external pageJ32, external pageJ37, external pageJ48). Our work further extended to foundation-structure systems, including physical modelling of a 3-storey building with artificial plastic hinges (external pageJ101), and pipelines (external pageJ89). Our research culminated to the development of design methods for foundations (external pageJ11, external pageJ12, external pageJ26), bridges (external pageJ17), and tunnels (external pageJ10, external pageJ24). Our methods have been applied to a number of projects of significance (25 bridges, 8 tunnels, and several important buildings).
