Abstract

The invention discloses two-shaft compression test equipment which comprises an axial load loading device, a square frame, a sample container, a first horizontal load loading device and a second horizontal load loading device, wherein the axial load loading device comprises fixedly arranged upper and lower reaction racks and an axial loading platform; the axial loading platform is arranged below the upper reaction rack and can be lifted; the square frame is arranged on the axial loading platform; the sample container is used for bearing a material sample and comprises a container bottom plate arranged on the square frame, left and right press plates with two ends capable of respectively horizontally moving and a loading cover plate arranged at the top and capable of moving along the vertical direction. The two-shaft compression test equipment is applicable for the two-dimensional ideal granular materials and can respectively apply positive stress in two orthogonal directions to realize different loading routes without considering the rotation of the stress main shaft.

Description

technical field [0001] The invention relates to the field of material analysis, and is particularly suitable for testing the mechanical properties of soil materials under complex loading conditions and ideal granular materials in the study of soil mechanics and granular medium mechanics. Background technique [0002] In engineering practice, its safety mainly depends on the deformation, strength and stability of engineering materials and structures. As the most widely used material, foundation or environment in engineering construction, soil is inseparable from the safety of engineering construction. Soil material unit test is the most basic means to evaluate the relationship between soil material deformation strength characteristics and mechanics. The conventional triaxial instrument is the most commonly used unit test equipment for soil materials at home and abroad. The equipment is limited to routine test paths such as triaxial compression and elongation. However, in a...
