| Abstract: | Friction forces of earth acting on the anchor bar of bridge dais have been measured as long as 20 hours on the spot. Many experimental data have been obtained in this testing. The variation regularity of the tension with length, time, temperature and weld joints after tensing, as well as the changes and distribution of the friction forces of earth have been researched and analyzed. The results of this research and testing have important theoretical and practical values for directing to the design and construction of similar structures. |
