Improving Agreement Between Static Method and Dynamic Formula for Driven Cast-In-Place Piles in Wisconsin, Brief.

摘要

These were the objectives of this research project: (1) Provide needed data and analyses to help WisDOT determine the effects of changing to the AASHTO LRFD methodology and also changing from the modified-EN pile installation method to the modified Gates or Washington State method. (2) Provide data and recommendations on appropriate modifications to the AASHTO suggested design factors used in LRFD, based on local conditions and past experience. (3) Compare, quantify and improve the agreement between as-designed and as-driven pile lengths.
