Compatible with test specimens up to 300mm in diameter! Tests for gravel, coarse-grained materials, and deep ground.
To accurately grasp the strength and deformation characteristics of ground composed of coarse-grained materials such as gravel, it is necessary to conduct tests using specimens of dimensions corresponding to the gravel diameter. The "Repeated Large Triaxial Testing Machine" has been developed to accommodate specimens up to 300mm in diameter. It also has the loading capacity to handle high-strength materials such as soft rocks. In this test, static strength and liquefaction strength, as well as repeated deformation characteristics, permeability coefficient, shear wave velocity, axial strain measurement using LDT, and Poisson's ratio constants can be obtained. 【Obtained Constants】 ■ Static Strength: C, φ ■ Liquefaction Strength: Rl ■ Repeated Deformation Characteristics: G～γ, h～γ ■ Permeability Coefficient: k15 ■ Shear Wave Velocity: Vs ■ Axial Strain Measurement using LDT: E, ε1 ■ Poisson's Ratio: ν *For more details, please refer to the PDF document or feel free to contact us.
