Single-pile horizontal static load test device and method under composite load effect
The invention relates to the technical field of building construction, in particular to a single-pile horizontal static load test device and method under the composite load effect. The device comprises a test pile foundation and a test loading device, the test pile foundation comprises a test pile and a pile foundation bearing platform, and foundation bolts are embedded in the pile foundation bearing platform according to the position of a perforated steel plate; the test loading device comprises an H-shaped steel beam and electric hydraulic jacks, and the electric hydraulic jacks are fixedly arranged on the test pile and the H-shaped steel beam respectively. Compared with a traditional pile foundation bearing capacity test method and device, the method solves the problem that the vertical bearing capacity and the horizontal bearing capacity of the pile foundation are measured respectively; the device solves the problem that the actual stress state of the pile foundation cannot be actually reflected, can effectively measure the actual stress state of the pile foundation under the action of the composite load, and is very important for short piles, especially for heliostat pile foundations with extremely high requirements for stability and precision.
本发明涉及建筑施工技术领域，尤其是涉及一种复合荷载作用下的单桩水平静载试验装置及方法。所述装置，包括试验桩基础和试验加载装置，其中，所述试验桩基础包括试验桩和桩基础承台，所述桩基础承台上按照开孔钢板位置预埋有地脚螺栓；所述试验加载装置包括H型钢梁和电动液压千斤顶，所述电动液压千斤顶分别固定设置在试验桩和H型钢梁上，本发明与传统桩基承载力的试验方法和装置相比，该方法解决了桩基础竖向承载力和水平承载力分别测量，不能实际反应桩基础的实际受力状态的问题，能有效的测量桩基础在复合荷载作用下的实际受力状态，对短桩尤其是对稳定性和精度有极高要求的定日镜桩基础非常重要。
