The experimental research and analysis of the friction forces of the earth acting on the anchor bar of anchor bridge dais

摘要

The friction forces of earth acting on the anchor bar of bridge dais have been measured for 20h insitu. It has been found thatthe anchroage tension varies with time and temperature, as well as with the changes and distribution of the friction forces of earth. The results of this research can be used to improve design and quality of engineering.
