Abstract
Large scale failures of pile foundations driven in liquefiable soil deposits have been reported during the 1964 Alaska and Nighaata Earthquakes. Where the subsoil did not liquefy, the piles did not fail. These conclusions were the basis of selection of a proper pile type for the Bonoaigaon Complex wherein it was intended that the pile installation procedure shall also adequately densify the loose saturated sandy and silty subsoils prone to liquefaction during expected earthquakes at site. Studies were carried out to assess soil characteristics before and after piling and the resulting improvement in the subsoil. It is concluded that the subsoil densification achieved after piling is adequate to guard against possibility of liquefaction occurring within pile groups and thus ensure the safety of the piles.

Large scale failures of pile foundations driven in liquefiable soil deposits have been reported during the 1964 Alaska and Nighaata Earthquakes. Where the subsoil did not liquefy, the piles did not fail. These conclusions were the basis of selection of a proper pile type for the Bonoaigaon Complex wherein it was intended that the pile installation procedure shall also adequately densify the loose saturated sandy and silty subsoils prone to liquefaction during expected earthquakes at site. Studies were carried out to assess soil characteristics before and after piling and the resulting improvement in the subsoil.
