An Instrumented Becker Penetration Test for the Estimation of Soil Penetration Resistance and Pile Capacity in Gravelly Soils
The recently developed instrumented becker penetration test (iBPT) can provide direct measurements of force and acceleration directly behind the driving shoe and at up to four locations along the drill string. This paper describes details of the test system and presents representative results from iBPT soundings performed at a project site where piles, supporting a bridge deck, were installed in relatively clean gravelly soils to a depth of approximately 18 m. The ability of the iBPT system to estimate equivalent SPT N60 values is demonstrated. Dynamic data from individual hammer blows obtained at the tip and along the shaft, as well as fitting of the data with simple spring-dashpot model is presented. Finally, results from static tension load tests showing the measured load distribution along the pile length is presented.
