摘要
本文对锚拉桥台的锚拉杆进行了长达２０小时的现场监测试验。对张拉后锚拉杆的张力随时间、温度的变化规律、土摩阻力的变化及分布规律作了分析与研究。为完善锚拉桥台体系的优化设计及提高工程质量提供了有效的依据。
Friction forces of earth acting on the anchor bar of bridge dais were measured for 20 hours on the spot. The variation of the tension with bine and temperature after mounting, as well as the distribution of the friction forces of end were studied. It is believed that the results of this research and testing is useful in improving design and construction
