Abstract

The invention relates to the related technical field of tests, and discloses a high-moisture-content soil vibration triaxial test sample preparation method and a sample preparation device. The high-moisture-content soil vibration triaxial test sample preparation device comprises a fixed base, a movable base matched with the fixed base is movably installed on one side of the surface of the fixed base, and locking rods are movably installed on the two sides of the fixed base correspondingly; pins are movably connected to the two sides of the top end of the fixed base correspondingly, the movable base is fixedly connected with the fixed base through the pins, a three-section mold is movably installed on the inner wall of the movable base, a top base is movably installed at the top end of the three-section mold, driving handles are movably installed on the two sides of the top base, and a compactor is movably installed at the top end of the top base. The movable base and the fixed base are convenient to disassemble through the pins, so that the movable base and the fixed base can be disassembled from the characteristic of high-water-content soil, layered sample compaction is finally achieved, and the problems that a soft sample is difficult to prepare and difficult to completely take out are solved.

Description

technical field

[0001] The invention relates to the technical field related to testing, in particular to a sample preparation method and a sample preparation device for high moisture content soil vibration triaxial tests. Background technique

[0002] The dynamic characteristics of sandy soil in railway embankment engineering are very important to the function of the embankment. Vibration triaxial test is one of the common methods to study the dynamic characteristics of soil. A more scientific basis has been established. The vibration triaxial test often carried out indoors includes the dynamic deformation characteristic test and the dynamic strength test. The strength test is to study the development trend of the dynamic pore water pressure of the soil under the action of dynamic load, and to measure the dynamic cohesion and dynamic internal friction angle of the soil. Provides a solution to the problem of earthquake resistance.
