Improved Field Methods for Estimating Pile Bearing Capacities. Putting Research to Work Brief.

摘要

In order to provide support for Wisconsin’s bridges and other structures, the concrete-encased cast-in-place piles or steel piles that serve as their foundations must be installed into the ground. Engineers need to predict a pile’s axial capacity during construction, which is based on the resistance of the pile during installation. If actual pile capacity differs from predicted pile capacity, then either the piles may not be installed deep enough to meet desired safety levels, or the piles may be driven too deep, which wastes time, labor and materials.
