Problems solved by technology

Because this loading technique naturally has the disadvantage of being unable to decouple the axial load and inertial load from the superstructure, the research on the physical model test of the seismic load effect on pile foundations has been slow.

Abstract

A shaking table test loading device with load decoupling function and a use method thereof belong to the technical field of shaking table tests. The counterweight column foot is set on the outside of the vibration table, and is connected with the side limit frame through a hollow steel pipe. The pile head baffle is set on the pile head of the model pile. Placed on the pile head baffle and has a pulley fitted to the side limit frame and the pile head baffle. Design and prefabricate the size of each component, put the pile head baffle on the pile head of the model pile, apply lubricating oil to the pile head baffle and side limit frame, determine the position of the counterweight column foot and assemble all the parts one by one. The guide car is placed in the side frame, and the quality blocks are placed in the guide car. The invention eliminates the influence of the inertial load from the superstructure while axially loading the model pile, greatly improves the execution efficiency of the test, is quick to install and easy to disassemble, and is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to a vibration table test loading device with a load decoupling function and a use method thereof, belonging to the technical field of vibration table tests. Background technique [0002] Since 2000, my country's mainland has entered a new period of seismic activity, with an average of 20 earthquakes of magnitude 5 or above, 3.8 earthquakes of magnitude 6 or above, and 0.6 earthquakes of magnitude 7 or above, and the damage to pile foundation structures is serious. Therefore, the seismic response analysis of pile foundation engineering has become an important and concerned scientific issue. [0003] Loading of pile foundations under earthquake is an extremely complex problem, which often involves a series of simultaneous and mutually compensating loads, including axial loads from the superstructure, inertial loads, and pile-soil dynamic interactions. [0004] In order to ascertain the load mechanism and failure mechanism of pile ...
