Reliable results depend on satm factors, Practice D provides a means of d507 some of those factors. The constant normal load boundary condition may not be appropriate for problems where shearing is dilatancy controlled and the normal stress is not constant along the discontinuity.

Reporting of test results in units other than SI shall not be regarded as nonconformance with this test method. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Active Risk Management

The test is usually conducted in the undrained state with an applied constant normal load. The apparatus consists of a shear box designed to accept samples not larger than x mm, or alternatively cores up to mm dia. Two versions are available:. The actual contact areas during testing change, but the actual total contact surface is unmeasurable.

The constant normal load boundary condition is appropriate for problems where the normal stress is constant along the discontinuity. Results Produced Report of direct shear strengths five to nine pages depending on sample type including the following: When the normal force is not sufficient to restrain dilation, the shear mechanism consists of the overriding of the asperities.

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. However, a clean, open discontinuity may be free draining, and, therefore, a test on a clean, open discontinuity could be considered a drained test.

For more info please refer to Releted Products below and Accessories section. ASTM D Use This test method establishes requirements and laboratory procedures for performing direct shear strength tests on rock specimens.

Therefore nominal area is used d56077 loading purposes and calculations. Note 2—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. Two versions can be used to complete the testing configuration: Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times.

Two set of cables are required. Samples should be concrete or rock cores with a diameter no greater than 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. Active view current version of standard. Link to Active This link will always route to the current Active version of the standard.

Historical Version s – asrm previous versions of standard. It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering design.

Therefore, the precise prediction of rock mass behavior is difficult. However, a clean, open discontinuity may be free draining, and, therefore, a test on a clean, open discontinuity could be considered a drained test. The shear box consists of two halves, the upper being connected to two rams for reversible shearing action and the lower connected to a ram for normal load application.

Relationships derived from the test data include shear strength versus normal stress and shear stress versus shear displacement shear stiffness. This test method establishes requirements and laboratory procedures for performing direct shear strength tests on rock specimens.

Therefore, it may be 5d607 to handle specimens in accordance with Practice D and to document moisture conditions in some manner in the data collection.

Clearly label the sample with source, date taken, intact or sliding friction, and a short, unambiguous, identification code. Therefore nominal area is used for loading purposes and calculations. During the test, shear strength is determined at various applied stresses normal to the sheared plane and at various shear displacements.

Examples of an artificial discontinuity include a rock-concrete interface astj a lift line from a concrete pour. Print and complete the following order form. The actual contact areas during testing change, but the actual total contact surface is unmeasurable.

It includes procedures for both intact rock strength and sliding friction tests which can be performed on specimens that are homogeneous or have planes of weakness, including natural or artificial discontinuities. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Users of this standard are cautioned that compliance with Practice D does not in itself assure reliable results.

Report of direct shear strengths five to nine pages depending on sample type including the following:. It includes procedures for both intact rock strength and sliding friction tests which can be performed on specimens that are homogeneous, or have planes of weakness, including natural or artificial discontinuities.

Sliding on and shearing of the asperities can occur simultaneously. Samples should be sealed in a plastic wrap inside their shipping container, protected against air, moisture, and direct sunlight.
