The invention provides a pile top restraint device for a horizontal load test, which comprises reaction racks positioned around the pile foundation, fixed with the lab foundation and also fixedly connected with a track frame assembly, wherein a separated fixed box is arranged in the track frame assembly and sleeved on the pile top; a horizontal loading device is arranged on the side edge of the separated fixed box; and the fixed separated box comprises a plurality of separated box bodies capable of horizontally moving on the track frame assembly, and a fastening structure for locking the separated box bodies, and the separated box bodies are fixed with the pile top through the fastening structure. The invention further provides a pile top restraint method. According to the method and the device provided by the invention, as the pile top is restrained, when the horizontal load is loaded, the pile top only moves horizontally, without moving in other directions or generating corner rotating, so that the stressing and deformation of the pile foundation during practical engineering can be simulated to the utmost.
Description
technical field [0001] The invention relates to a horizontal load test pile top constraint device. [0002] The invention also relates to a pile top restraint method for a horizontal load test. Background technique [0003] The static load test of pile foundation is to apply vertical pressure, vertical uplift force or horizontal thrust step by step on the top of the pile, and observe the settlement, uplift displacement or horizontal displacement of the pile top over time to determine the corresponding vertical resistance of the single pile. Test methods for compressive capacity, vertical uplift capacity of a single pile or horizontal capacity of a single pile. Static load test of pile foundation, including vertical compressive load test of single pile, vertical pull-out load test of single pile, horizontal load test of single pile. [0004] The single pile horizontal load test adopts the test method close to the actual working conditions of the horizontally loaded pile to ...
