The site of a warehouse expansion in Tampa, Florida was underlain by sand overlying limestone. The performance criteria required ground improvement to densify the upper sand in order to maintain a maximum total settlement of 25 mm (1 inch) for an applied subgrade ...

Since its introduction in 1973, the Davisson Offset Limit has been widely used in the United States for interpretation of axial compressive load tests on pile foundations and is one of three methods explicitly accepted by the 2006 International Building Code. ...

Drilled displacement piles are installed by the displacement of soil and subsequent placement of fluid cement grout within the evacuated volume. Depending on the soil grain-size characteristics, soil behavior, in situ soil density, pile spacing, and pile diameter, ...

Drilled displacement piles (also known as augured cast-in-place displacement piles or augured, pressure-injected displacement piles) are installed by the displacement of soil and subsequent placement of cement grout within the evacuated volume. Depending on ...

This paper examines the conditions prior to and following the installation of drilled displacement piles at sandy sites using the cone penetration test. The data support that the installation of drilled displacement piles results in a substantial increase ...
