Augered cast-in-place piles, also known as ACIP piles, have been used for more than
seven decades in the United States and have gained in popularity due to their relatively
quick installation and cost-effectiveness. Owing to the reduced impact on the neighboring
environment as compared to some other deep foundation installation...
Deep foundations are necessary for the construction of many structures, such as bridges and buildings, located in areas unsuitable for shallow foundations. Owing to the inherent variability of soil and the complex changes that occur in the soil adjacent to deep foundations as they are installed, the ability to accurately...
Recent experience demonstrates that waterfront structures are vulnerable to
earthquake damage. The poor seismic performance of these facilities has been
primarily due to liquefaction of backfill and/or foundation soils and the lack of
seismic design standards for waterfront structures. The seismic performance of
waterfront structures is a key issue in...
Drilled shaft foundations provide significant geotechnical resistance for support of structures, such as highway bridges, traffic sign, and signal pole structures, and are used widely to meet their structural foundation requirements. The amount of steel reinforcement in drilled shaft foundations has increased over the past several decades to account for...
