triaxial test การใช้

Triaxial tests are used along with other tests to make such engineering predictions.
He worked extensively in the field of experimental Soil mechanics and developed apparati for soil testing, such as the triaxial test and the ring shear.
From the triaxial test data, it is possible to extract fundamental material parameters about the sample, including its angle of shearing resistance, apparent cohesion, and dilatancy angle.
Facilities for mining engineering, tunnelling, surveying and geotechnics include underground and surface testing facilities; Leica surveying equipment, a Leica / DMT Gyromat 2000 Precision Gyrotheodolite, and a triaxial test rig.
This is typically achieved by placing the sample between two parallel platens which apply stress in one ( usually vertical ) direction, and applying fluid pressure to the specimen to apply stress in the perpendicular directions . ( Testing apparatus which allows application of different levels of stress in each of three orthogonal directions are discussed below, under " True Triaxial test " .)
