Earthquake simulation platform monitoring device for engineering pile foundation

Abstract

The invention discloses an earthquake simulation platform monitoring device for an engineering pile foundation. The earthquake simulation platform monitoring device comprises an earthquake simulationplatform, a cylinder arranged above the earthquake simulation platform and at least one engineering pile foundation arranged in the cylinder. A rotating disc is arranged in the middle of the top of the earthquake simulation platform, the rotating disc can rotate, the rotating disc can drive the cylinder to rotate in the rotating process, a plurality of supporting rods are arranged at the top of the rotating disc in the circumferential direction at intervals, the tops of the supporting rods are connected with the cylinder in a matched mode, and the cylinder is filled with liquefied soil; a plurality of calibration points are arranged in the outer side of the engineering pile foundation at intervals in the length direction, and at least one sensor is arranged at each calibration point; the sensor is connected to the outer side of the engineering pile foundation in a sleeving mode, and a plurality of weight stacks are arranged at the top of the engineering pile foundation and distributedin a staggered mode.

Description

technical field [0001] The invention relates to the fields of engineering foundation monitoring and building pile foundation monitoring, in particular to an earthquake simulation platform monitoring device for engineering pile foundations. Background technique [0002] Earthquakes, also known as ground motions and ground motions, are natural phenomena in which seismic waves are generated during the rapid release of energy from the earth's crust, and different levels of earthquakes will have different degrees of impact. The place where the earthquake begins to occur is called the epicenter. The ground directly above the epicenter is called the epicenter; the place where the ground vibration of a destructive earthquake is the strongest is called the episeismic area, which is often the area where the epicenter is located; severe earthquakes can cause casualties, and can cause fires, floods, poisonous Gas leakage, bacteria and radioactive material diffusion may also cause second...

AI Technical Summary

Problems solved by technology

[0003] The traditional monitoring device does not determine the calibration point of the engineering pile foundation, and the sensor is not fixed on the engineering pile foundation by socketing, the monitoring accuracy is poor, the weight sheet is not distributed through dislocation, and the engineering pile foundation is in the In the case of heavy load, the various positions on the top of the pile foundation are unevenly stressed
