Shaft side shearrock strenghtIn field and laboratory investigations, University of Florida researchers focused on developing and evaluating drilling parameter data as a means of estimating rock strength.Over the past 20 years, drilled shafts have demonstrated increasing popularity over driven precast piles...
The shaft capacity of a pile depends on the stress state of the soil surrounding the pile that results after its installation. Proper analysis of the impact of installation of DD piles on the stress state in the in situ soil is fundamental to the development of reliable design methods. This...

Civil engineering Analysis of shaft resistance of jacked and drilled-displacement piles PURDUE UNIVERSITY Monica Prezzi BasuPrasenjitSignificant developments in piling technology over the last few decades have yielded a variety of new pile types. Jacked and Drilled-Displacement (DD) piles, for example,...
Additionally, setup factors are proposed that can be used to estimate the gain in shaft resistance as a function of time after installation of jacked piles in clay. Good agreement was obtained between the shaft resistance values calculated with the proposed equations and the data available in the...
