Design And Applications Of Drilled Displacement (Screw) Piles, Prasenjit Basu, Monica Prezzi
JTRP Technical Reports
Drilled displacement (DD) piles (commonly known as „screw piles‟ in Europe) are being increasingly used as foundation elements for structures, particularly in projects requiring accelerated construction or involving the rehabilitation of foundations of existing, overstressed structures. Different types of DD piles are available in practice; each type is classified according to the design of the drilling tool and associated installation method. Installation of DD piles causes substantial changes in the state of the soil surrounding the pile. These changes result from the complex loading imposed on the soil by expansion of a cylindrical cavity to make room for the specially …

JTRP Technical Reports
When piles are installed by jacking or driving, they cause substantial changes in the state of soil located near the pile. These changes result from the complex loading imposed on the soil by expansion of a cylindrical cavity to make room for the pile, by multiple cycles of shearing in the vertical direction as the pile gradually moves down into the ground, and by the slow drainage associated with clayey soils. If a pile is load-tested a short time after installation, it will develop an axial resistance that reflects the existence in the soil of the excess pore pressures caused …

Cemented carbonate deposits (known locally as "caliche") in Las Vegas have been used to support shallow and deep foundations with relatively high bearing pressures compared to soil. Most high rise structures in Las Vegas are founded on either a large mat or a long pile foundation. Recently, a new foundation type consisting of a short pile system bonded to shallow cemented layers was utilized for a large high rise building in Las Vegas and settlements during construction were recorded. The bonding of caliche layers together with short piles forms a caliche stiffened pile (CSP) foundation. The CSP foundation is unique …
