Adjustable loading device for pile foundation horizontal static load test and test method
The invention relates to an adjustable loading device for a pile foundation horizontal static load test. The adjustable loading device comprises a loading system, a counterforce system, and a measurement system; the loading system consists of a centre hole jack, a bearing screw, a force transferring nut, a cross beam, and two cross beam brackets; the cross beam is of a steel truss structure, and radial circular through holes are formed in the middle of the cross beam at equal intervals; the counterforce system is composed of a standard channel, two triangular counterforce frames and counterforce frame fixing screws; the side faces of the two triangular counterforce frames are opposite, the two triangular counterforce frames are arranged in parallel, and the triangular counterforce frames are fixed to the standard channel through the counterforce frame fixing screws, and the cross beam is disposed on the cross beam brackets and abuts against the stress surfaces of the counterforce frames; one end of the bearing screw sequentially passes through the force transferring nut, the centre hole jack and a cross beam longitudinal centre hole to be connected with a force sensor and a test pile, and the side, away from the pile, the jack is connected with the force transferring nut; and the force sensor is connected with a computer through a dynamic strain meter. The adjustable loading device can meet test requirements of multiple different pile foundations under existing test foundation pit and channel conditions.
本发明涉及一种用于桩基水平静载试验的可调加载装置，包括加载系统、反力系统和测量系统；加载系统由穿心千斤顶、承载螺杆、传力螺母、横梁和两个横梁托架组成；横梁为钢桁架结构，横梁中部等间距设置有径向圆形通孔；反力系统由标准槽道、两个三角反力架和反力架固定螺杆组成；两个三角反力架侧面相对、平行设置，通过反力架固定螺杆固定在标准槽道上，横梁搁置在横梁托架上并靠紧在反力架受力面；所述承载螺杆一端依次穿过传力螺母、穿心千斤顶、横梁纵向穿心孔，与力传感器、试验桩连接，千斤顶远桩侧与传力螺母联接；力传感器通过动态应变仪与计算机连接。本发明在现有试验基坑和槽道条件下可满足多种不同桩基的试验要求。
