Simulated seismic experiment platform

Abstract

The invention discloses a platform which can reconstruct a series of motion phenomena happened to epicentral areas and peripheral grounds near the epicentral areas and destructive effects caused by the motion phenomena. The platform is composed of a fixed revolving shaft, a seismic focus block, an air space, a pulling pile, a pulling rope, a cobble layer and a common stratal substance layer, wherein the seismic focus block is overlaid on the fixed revolving shaft and is in an overhead state, the air space is adjacent to the seismic focus block, the pulling pile and the pulling rope are used for keeping the seismic focus block in the overhead state and restoring the seismic focus block to the overhead state, the cobble layer is overlaid on the upper surface of the seismic focus block, and the common stratal substance layer is arranged on the cobble layer. The platform is characterized in that the distance between a limit pile and the seismic focus block is set according to a required surface intensity, after the pulling rope is loosened, the seismic focus block naturally inclines to the air space side under the action of gravitational attraction so as to drive the ground of the platform to produce motion scenes and intensities of the epicentral areas and the peripheral grounds near the epicentral areas when earthquakes occur; the seismic focus block can be restored to the normal position by the pulling actions of the pulling pile and the pulling rope, then the seismic focus block is in the overhead state again, and a new simulated seismic experiment can start again. The platform provided by the invention can provide objective and accurate data for tests on seismic materials, seismic structures and the like.

Description

Technical field [0001] The invention relates to an experimental device for artificially generating earthquake damage effects, in particular to an experimental platform capable of generating shaking, jolting, initial cracks, uplifts, fan-shaped arc movements, final cracks, subsidence and other ground phenomena in the epicentral area. Background technique [0002] At present, known seismic test platforms are driven by motors for horizontal shaking, and some have complicated horizontal shaking into torsion, plus various types of vibrations, fluctuations, etc., to test the seismic performance of building materials and building structures. However, before I wrote "Focal Tectonic Earthquake Mechanism" and "Prediction, Forecast and Prevention Methods of Series Earthquakes", people's understanding of the nature of earthquake destructive force has not reached its essence. They only know that the ground will shake horizontally during an earthquake, and it is estimated that there is a c...

Problems solved by technology

[0003] In order to overcome the defect that the existing anti-seismic experimental platform cannot reproduce the destructive effect of the earthquake epicentral area and its nearby high-intensity area, the invention provides a simulated earthquake experimental platform, which can produce multiple levels of surface intensity, especially high-intensity The graded surface intensity can not only simulate the approximate horizontal shaking of the ground outside the epicenter area and the resulting destructive force, but also simulate the shaking, turbulence, initial crack, uplift, fan-shaped arc movement, final crack, and back and forth shaking of the ground in the epicenter area. , sinking, vibration and a series of motion phenomena and the resulting destructive force
