New Technological and Design Developments in Deep Foundations

Proceedings of sessions at Geo-Denver 2000, held in Denver, Colorado, August 5-8, 2000. Sponsored by the Geo-Institute of ASCE.

This Geotechnical Special Publication contains 34 papers presenting the latest information on the design, installation, and performance of deep foundations. Special emphasis is placed on post-grouted drilled shafts and on augered, cast-in-place (ACIP) piles. Papers on screwed and driven foundations are also included.

Topics include:

• high-capacity piles on rock;
• design, installation, and performance of helical piles;
• post-grouting of drilled shafts;
• lateral load considerations for drilled and ACIP piles;
• resistance factors for driven piles;
• pile load test databases;
• neural networks and pile design;
• remediation techniques using piles;
• numerical analyses of drilled shafts and ACIP piles;
• comparison of pile and probe tests;
• prediction of pile set-up;
• nondestructive testing of drilled shafts;
• p-y curves in partially saturated soils;
• design and testing of ACIP piles;
• quality control measures for ACIP piles; and
• properties of auger grout.
