摘要
通过对抗浮锚杆在基础结构中的后锚固进行研究与应用,提出了一种楔形锚固形式及后施工方法,并通过试验研究确定了楔形角对锚固力的影响。试验证明,楔形锚固体具有很强的抗拉拔能力,能够增大锚固体在基础中的锚固能力。同时结合工程实践,后施工方法有效加快了施工进度,增强了基坑稳定性,缩短了地基暴露时间。
Through the research and application of post-installed anti-floating anchor pile of foundation,a form of wedge anchorage and construction method is proposed in this paper,and the effect of wedge angle of anchoring force is determined by experiments. The experiment proved that the wedge anchor solid has strong anti drawing ability,and can increase the anchorage capacity of anchor solid in foundation. At the same time,the construction method can effectively accelerate the construction progress,enhance the stability of the foundation excavation,shorten the foundation exposure time in practical engineering.
