Abstract

The invention discloses a soil triaxial test saturated sample filling method, which comprises a stainless steel barrel and a plastic film, the inner cavity of the stainless steel barrel is provided with a plastic film, and a plurality of plastic films are evenly distributed between the plastic film and the stainless steel barrel The inner cavity of the plastic film is provided with a soil sample bucket, the soil sample bucket is arranged in three petals, and the center of the outer side wall of the soil sample bucket is provided with a tight hoop. The method of the invention is convenient for sample loading operation, can effectively improve the saturation of soil sample loading, thereby effectively reducing errors and improving the accuracy of sample experiments; the device of the invention can more truly restore the real mechanical parameters of soil samples in the field , so as to provide more reliable theoretical data for slope stability research. The present invention has the 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 method for saturated soil loading in a triaxial test. Background technique [0002] Shear strength refers to the strength limit when the external force is perpendicular to the material axis and acts on the material in shear; or refers to the maximum ability to resist shear damage. The shear strength of soil refers to the ultimate strength of soil to resist shear failure. It is an important mechanical property of soil, and it is also a necessary parameter for earth pressure calculation, soil dam slope stability calculation, and backfill strength calculation. The shear strength of soil can be calculated by the following formula: In the formula, φ is the angle of internal friction, c is the cohesion of the soil, which is the constituent factor of the shear strength of the soil. It can be determined by direct shear test or triaxial compression test of soil. Acco...
