Abstract

The invention provides an annular shearing experiment equipment and a testing method, the annular shearing experiment equipment includes a support seat, a shear box assembly located on the support seat, and a load applied to soil samples in the shear box assembly The loading device, the loading device includes a vertical vibration loading device and a horizontal shear vibration loading device, and the annular shear experimental equipment further includes a load control device for controlling the loading of the vertical vibration loading device and/or the horizontal shear vibration loading device. device. The vertical vibration loading device and/or the horizontal shear vibration loading device can apply vibration loads of different frequencies and amplitudes, which is beneficial to study the influence of dynamic loads on soil strength parameters, more conducive to simulating the actual stress situation, and conducive to revealing The stress changes, pore water pressure changes, local soil damage and liquefaction phenomena occurred during the shear test of the soil under the action of vibration loads, and then reveal the occurrence and movement mechanism of geological disasters such as landslides from the mechanical properties.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering experiment equipment, and in particular relates to an annular shearing experiment equipment and a test method. Background technique [0002] my country is one of the countries most severely affected by landslide disasters in the world. The occurrence of landslide disaster is a complex mechanical process and is affected and controlled by many factors, among which the dynamic load such as earthquake is one of the most important influencing factors. 41272341). At present, the research on the mechanical properties of soil in landslide hazards mainly focuses on the determination of engineering properties and strength parameters of sliding zone soil. The basic strength parameters of the sliding zone soil were determined by means of statistics, analogy and inversion analysis by means of on-site in-situ tests and indoor conventional geotechnical tests, and were used to evaluate the stab...
