Single-pile vertical anti-pulling static load experiment method
The invention discloses a single-pile vertical anti-pulling static load experiment method, and belongs to the field of pile foundation detection technology, the single-pile vertical anti-pulling static load experiment method adopts an oil jack to load an anti-pulling pile, and adopts a full-automatic static load tester to record the load and pile top displacement data. The load loading method of the static load test is a low-speed load maintaining method, loads are applied to the uplift pile step by step, the next stage of load is added every time when the vertical deformation of the pile top reaches a stable state until the maximum load of the test is added, and then the load is unloaded to zero step by step. According to the single-pile vertical uplift static load experiment method disclosed by the invention, the uplift bearing capacity of the uplift pile can be effectively tested. Therefore, the single-pile vertical uplift static load experiment method solves the technical problem of how to accurately detect the uplift bearing capacity of the uplift pile.
本发明公开了一种单桩竖向抗拔静载实验方法，其属于桩基检测技术的领域，本发明单桩竖向抗拔静载实验方法采用油压千斤顶对抗拔桩进行加载，并采用全自动静载测试仪来记录所加荷载和桩顶位移数据。该静载试验的荷载加载方法为慢速维持荷载法，逐级对抗拔桩施加荷载，每加一级荷载等到桩顶竖向变形量达到稳定状态后再加下一级荷载，直至加到试验最大荷载，然后，再分级卸载到零。通过本发明所揭示的单桩竖向抗拔静载实验方法可以有效地对抗拔桩的抗拔承载力进行测试。所以，本发明单桩竖向抗拔静载实验方法解决了如何准确检测抗拔桩的抗拔承载力的技术问题。
