High slope support anti-seismic experiment device and experiment method

Abstract

The invention discloses a high slope support anti-seismic experiment device and method, and the device comprises a vibration table, the vibration table is provided with an outer frame, and the outer frame is internally provided with an inner frame through a plurality of supporting rods; the inner frame comprises a bottom surface, two opposite sides of the bottom surface are respectively a low surface and a back slope surface, and two sides of the back slope surface are respectively adjacent to the observation surface; a plurality of mounting holes are formed in the inner frame, and the mounting holes are filled with fixing blocks; the test method comprises the following steps: manufacturing a soil body model in the inner frame, and arranging a strain sensor in the inner frame; installing each monitoring system according to the soil body model; after standing for a set time length, starting the vibration table and heating the machine; and inputting a set seismic waveform into the vibration table, and adjusting the acceleration value according to the setting until the set test content is completed. The problem that an earthquake simulation experiment device in the prior art is not suitable for a high and steep slope can be solved, covering influence factors are comprehensive, testing is reliable, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to an anti-seismic experimental device and an experimental method for high slope support. Background technique [0002] The study on the seismic stability of high and steep slopes is one of the important topics in geotechnical engineering. At present, the adaptation to the seismic stability of high and steep slopes at home and abroad is mainly through conventional rock mass model experiments to obtain data, but the existing experimental devices When simulating earthquakes, it is mainly suitable for conventional slope structures, but for high and steep slopes, due to the large differences in the distribution of rock formations, it is difficult to set up support structures, and it is inconvenient to observe and record, so the experimental results are not good. Contents of the invention [0003] The present invention aims at the above-mentioned deficiencies in the pr...
