Lecture

The presentation examined the increase in density in the vicinity of drilled displacement piles when they are installed in materials that exhibit granular behavior. The increase is most pronounced in loose to medium dense materials and can be utilized to mitigate liquefaction and increase the foundation response stiffness of the mass of the material penetrated.

This lecture examined the development and evolution of cast-in-place piles in the United States and Europe and described current industry equipment and installation practice. Conventional continuous flight auger (CFA) and drilled displacement piles were addressed.
