Abstract

The invention discloses a soil triaxial test saturated sample loading method. The method comprises a stainless steel barrel and a plastic film, wherein the plastic film is arranged in the inner cavity of the stainless steel barrel, a plurality of balls are uniformly distributed between the plastic film and the stainless steel barrel, a soil sample barrel is arranged in the inner cavity of the plastic film, the soil sample barrel is arranged in a three-section manner, and a tightening ring is arranged in the center of the outer side wall of the soil sample barrel. According to the method, the sample loading operation is convenient, and saturation of sample loading soil can be effectively improved, so errors are effectively reduced, and precision of a sample experiment is improved; the device provided by the invention can more truly restore the real mechanical parameters of the soil sample in the field, so more reliable theoretical data are provided for slope stability research. The method has advantages of high sample saturation and high precision.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a soil triaxial test saturated sample loading method. Background technique [0002] Shear strength refers to the strength limit when the external force is perpendicular to the axis of the material and acts on the material in shear; or refers to the maximum ability to resist shear damage. The shear strength of the soil refers to the ultimate strength of the soil against shear failure. It is an important mechanical property of the soil, and it is also a necessary parameter for the calculation of the earth pressure, the calculation of the stability of the slope of the earth dam, and the calculation of the strength of the filling body. The shear strength of soil can be calculated with the following formula: In the formula, φ is the internal friction angle, c is the cohesion of the soil, and is the constituent factor of the shear strength of the soil. It can be det...
