Samples should be sealed in a plastic wrap inside their shipping container, protected against air, moisture, and direct sunlight. Examples of an artificial discontinuity include a rock-concrete interface or a lift line from a concrete pour. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

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. Samples should be concrete or rock cores with a diameter no greater than Discontinuities may be open, partially or completely healed or filled that is, clay fillings and gouge. Clearly label the sample with source, date taken, intact or sliding friction, and a short, unambiguous, identification code.

During the test, shear strength is determined at various applied stresses normal to the sheared plane and at various shear displacements. Relationships derived from the test data include shear strength versus normal stress and shear stress versus shear displacement shear stiffness.

However, a clean, open discontinuity may be free draining, and, therefore, a test on a clean, open discontinuity could be considered a drained test. This test method establishes requirements and laboratory procedures for performing direct shear strength tests on rock specimens. For more info please refer to Releted Products below and Accessories section. Only one discontinuity per specimen can be tested.

Discontinuities may be open, partially or completely healed or filled that is, clay fillings and gouge. Therefore, the precise prediction of rock mass behavior is difficult. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Instructions Samples should be concrete or rock cores with a diameter no greater than The test is usually conducted in the undrained astk with an applied constant normal load.

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 aatm anisotropic and heterogeneous discontinuum.

When the normal force is not sufficient to restrain dilation, the shear mechanism consists of the overriding of the asperities. ASTM C5607 Use This test method establishes requirements and laboratory procedures for performing direct shear strength tests on rock specimens. Two versions can be used to complete the testing configuration: It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

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. The constant normal load boundary condition is appropriate for problems where the normal stress is constant along the discontinuity.

Therefore nominal area is used for loading purposes and calculations. 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. Two set of cables are required. Relationships derived from the test data include shear strength versus normal stress and shear stress versus shear displacement shear stiffness.

During the test, shear strength is determined at various applied stresses adtm to the sheared plane and at various shear displacements.

Link to Active This link will always route to the current Active version of the standard. 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.

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. Order Form 2 Email complete form to contact listed below. A summary of peak shear stress, peak residual shear stresses, and residual shear stresses A figure of peak residual aastm and residual shear stress vs. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

When the normal load is large enough to completely restrain dilation, the shear mechanism consists of the shearing off of the asperities. Reliable results depend on many factors, Practice D provides a means s5607 evaluating some of those factors. This apparatus was originally developed at Imperial college, London, by Professor E.
