摘要
文中主要介绍了改进的锚桩反力梁法和自平衡法大吨位桩基荷载试验测试技术,并通过工程实践证明预应力技术在锚桩反力梁法中的应用解决了锚桩抗拔能力不足和反力系统混凝土在高应力下开裂问题,改进的自平衡法试桩技术消除了荷载箱附近数据失真的问题,大大提高了自平衡试桩方法的准确性和可靠性。
This paper gives introduction to the improved anchor piles and reaction beam methods and self-balanced methods.At the same time,the paper also introduces the same cases that the technology of prestressing force has effectively solved the problems of anti-pull resistance capacity deficiency and cracks of anchor piles.The improvements of self-balanced method have eliminated the untruthful data and effectively improved the precision and reliability.
