Abstract
The invention provides a soil sample strength testing device and an experimental method thereof, comprising an installation frame, a shearing device fixed on the installation frame for placing soil samples, and a shearing device installed on the installation frame and used for feeding the soil samples in the shearing device The normal loading device for applying longitudinal load and the lateral loading device installed on the mounting frame for applying lateral load to make the shearing device shear the soil sample; the shearing device includes an upper shearing box, two transparent collars and a lower shearing device Box; both the upper shear box and the lower shear box are provided with stepped holes used in cooperation with each other and used to install the transparent collar, and the smaller diameter of the stepped hole is the same as the inner diameter of the transparent collar; the transverse direction along the axis of the transparent collar The section is rectangular; the upper shear box and the lower shear box are provided with observation ports on the sides, and the observation ports are located at the larger aperture of the step hole.
Description
technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a soil sample strength testing device and an experimental method thereof. Background technique [0002] In geotechnical engineering, the strength of the weak filling medium of the slope soil plays an important role in its stability. Engineering practice shows that there are primary fissures caused by non-expansion-contraction deformation in some expansive soil regions. The tendency of these fissures is mostly consistent with the topography, and they are either concentrated in a certain underground layer, or distributed in a certain strip of the stratum. The lengths of the fissures vary, and the extension direction of the fissures presents a certain regularity. In the natural state, these fissures are closed and are usually composed of soft filling media, such as gray-white or gray-green clay, and the thickness of the soft filling medium is mostly concentrated in...
