Rock sample sealing method for hard rock true triaxial test
ActiveCN103822809AControl UniformityAvoid breakingPreparing sample for investigationTriaxial shear testRock sample
The invention relates to a rock sample sealing method for hard rock true triaxial test, and belongs to the technical field of the hard rock true triaxial test. By additionally arranging groove chamfer angles at edges of pressure-bearing blocks and additionally arranging a step slot at a contact surface of every two adjacent pressure-bearing blocks, and at the same time, making the thickness of each pressure-bearing block larger than that of a rock sample, uniformity of a glueing layer can be well controlled by the difference between the thickness of the pressure-bearing block and the rock sample. Seal glue at the groove chamfer angles completely cover gaps on the contact surfaces of the pressure-bearing blocks and the rock sample, so that the glueing layers of the gaps on the contact surfaces are prevented from cracking and microosmolarity of an oil liquid at weak points of the glueing layers is prevented. By additionally arranging sealing rubber strips in the step slots, adequate seal between gaps on the contact surface of two adjacent pressure-bearing blocks can be achieved; and the sealing rubber strips are coated by seal glue, thereby playing a role of double seal. The method reduces influences of oil liquid leakage on test results to the lowest, thereby increasing accuracy and reliability of test data.
