Abstract
This case history describes the design, installation, and mainly the performance of the deep foundation system of a new automobile plant and complex near Gölcük, Kocaeli, Turkey, which was under construction when the August 17, 1999 earthquake struck western Turkey. The plant is situated on geologically young deposits in a seismically active region, only 1 km to the epicenter of the MS = 7.4 Kocaeli earthquake. With the awareness of this unfavorable setting, the original foundation system was designed to have combinations of bored, cast-in-place piles; jet grout columns; and displacement stone columns, after a series of pre-design field-testing. The earthquake took place when most of the plant was already erected, but only one building, which was very close to the surface trace of the fault, sustained structural damage. On the other hand, the entire site underwent subsidence and lateral displacement due to faulting. An extensive testing and investigation program was adopted after the earthquake to verify the performance of the deep foundations and to reassess the soil conditions. It was then decided to proceed with the construction, only moving the damaged building away from the fault rupture line, and further improving the foundation design.
