摘要：	The Federal Highway's Geotechnical Research Program was formally initiated in the 1970's. During the early 1970's, FHWA field personnel and the State Highway Agencies (SHA) recognized the need for more definitive technology for solving various soil and foundation problems. This report gives an overview and summarizes the results of three geotechnical research programs. The project or program areas were: soil and rock behavior; bridge foundations; and ground improvement techniques. Items covered, for example in foundation engineering, include pile foundations, pile groups, drilled shafts, spread footings, and foundation load testing. Ground improvement efforts and soil and rock behavior are also given in appropriate detail. Outputs, including guidelines and implementation items, are given for the various topics covered. Finally, an outline of future geotechnical research needs is presented.
