Therefore, it may be necessary to handle specimens in accordance with Practice D and to document moisture conditions in some manner in the data collection.

Results Produced Report of direct shear strengths five to nine pages depending on sample type including the following: Shear box made in aluminium alloy Maximun axial and shear load capacity: Only one discontinuity per specimen can be tested.

Link to Active This link will always route to the current Active version of the standard. Sliding on and shearing of the asperities can occur simultaneously.

Samples should be concrete or rock cores with a diameter no greater than The test is usually conducted in the undrained state with an applied constant normal load. Two set of cables are required.

Since this test method makes no provision for the measurement of pore pressures, the strength values determined are expressed in terms of total stress, uncorrected for pore pressure. A summary of peak shear stress, peak residual shear stresses, and residual shear stresses A figure of peak residual stress and residual shear stress vs. Instructions Samples should be concrete or rock cores with a diameter no greater than Two versions can be used to complete the testing configuration: During the test, shear strength is determined at various applied stresses normal to the sheared plane and at various shear displacements.

Order Form 2 Email complete form to contact listed below. The actual contact areas during testing change, but the actual total contact surface is unmeasurable.

Report of direct shear strengths five to nine pages depending on sample type including the following:. Examples of an artificial discontinuity include a rock-concrete interface or a lift line from a concrete pour.

Print and complete the following order form.

Discontinuities may be open, partially or completely healed or filled that is, clay fillings and gouge. Discontinuities may be open, partially or completely healed or filled that is, clay fillings and gouge. The constant normal load boundary condition is appropriate for problems where the normal stress is constant along the discontinuity.

In situ direct shear testing limits the inherent scale effects found in rock mechanics problems where the laboratory scale may not be representative of the field scale. Note 1—The term “normal force” is used in the title instead of normal stress because of the indefinable area of contact and the minimal relative displacement between upper and lower halves of the specimen during testing.

ASTM D Use This test method establishes requirements and laboratory procedures for performing direct shear strength tests on rock specimens. Active view current version of standard. During the test, shear strength is determined at various applied stresses normal to the sheared plane and at various shear displacements.

The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used.

Rock shear box apparatus

However, a clean, open discontinuity may be free draining, and, therefore, a test on a clean, open discontinuity could be considered a drained test. Therefore, the precise prediction of rock mass behavior asgm difficult. Relationships derived from the test data include shear strength versus normal stress and shear stress versus shear displacement shear stiffness.

Historical Version s – view previous versions ast standard. Displacement and load readings shall be acquired by suitable datalogger that has to be add as accessory.

Examples of an artificial discontinuity include a rock-concrete interface or a lift line from a concrete pour. Two versions are available:. Pervasive discontinuities joints, bedding planes, shear zones, fault zones, schistosity in a rock mass, and genesis, crystallography, texture, fabric, and other factors can cause the rock mass to behave as an anisotropic and heterogeneous discontinuum.

Link to Active This link will always route to the current Active version of the standard. The actual contact areas during testing change, but the actual total contact surface is unmeasurable. The normal loading system is complete with an adjustable low friction pressure maintainer to absorb volume changes of the specimen during the shearing action and to ensure a constant vertical stress.
