Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] The present invention is a kind of three-way rigidly loaded true triaxial instrument, such as figure 1 As shown, it includes a fixed frame. A pressure chamber is set in the fixed frame. The pressure chamber is used to place soil samples. Horizontal loading mechanisms are installed on the front, rear, left, and right sides of the pressure chamber. The horizontal loading mechanisms are used to apply loads to the soil samples in the horizontal direction. The top of the chamber is provided with a longitudinal loading mechanism, which is used to apply load vertically to the soil sample, and a measuring mechanism is also provided on the pressure chamber, which is used to measure the deformation strength characteristics of the soil sample. Such as figure 2 and image 3 As shown, the pressure chamber includes four horizontal loading mechani...

Abstract

The invention discloses a three-way rigid loading true triaxial apparatus, which comprises a fixing frame, a pressure chamber is arranged in the fixing frame, the pressure chamber is used for placing a soil sample, horizontal loading mechanisms are arranged on the front, back, left and right sides of the pressure chamber, the horizontal loading mechanisms are used for applying a load to the soil sample in the horizontal direction, and a longitudinal loading mechanism is arranged on the top of the pressure chamber, the longitudinal loading mechanism is used for vertically applying a load to the soil sample, and a measuring mechanism is further arranged on the pressure chamber and is used for measuring the deformation strength characteristic of the soil sample. The problem that interference exists during three-way loading of the true triaxial apparatus in the prior art is solved.

Description

[0001] technology field [0002] The invention belongs to the technical field of geotechnical engineering testing equipment, and relates to a three-way rigid loading true triaxial instrument. Background technique [0003] At present, there are many equipments for geotechnical tests. Existing test instruments and equipment for measuring soil shear deformation strength characteristics include direct shear instrument, single shear instrument, triaxial instrument, torsional shear instrument, plane strain instrument and true triaxial instrument. The shearing instrument also includes a dynamic single shearing instrument, a dynamic triaxial instrument and a dynamic torsional shearing instrument. [0004] The currently widely used conventional triaxial test can simulate different confining pressure and drainage conditions, and can reflect the whole process of soil samples from stress deformation to sample failure. However, the conventional triaxial test simulates an ideal axisymmetri...
