Only one discontinuity per specimen can be tested. It is a simple and practical method of determining the strength and slope stability of rock, both in the field and d507 the laboratory. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are asfm provided as part of the standard.

Reliable results depend on many factors, Practice Atm provides a means of evaluating some of those factors. The actual contact areas during testing change, but the actual total contact surface is unmeasurable. Discontinuities may be open, partially or completely healed or filled that is, clay fillings and gouge.

The actual contact areas during testing change, but the actual total contact surface is unmeasurable. Historical Version s – view previous versions of standard. 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 are available:. Active view current version of standard. The constant normal load boundary condition is appropriate for problems where the normal stress is constant along the discontinuity. Print and complete the following order form. Samples should be sealed in a plastic wrap inside their shipping container, protected against air, moisture, and direct sunlight. Two set of cables are required.

Samples should be concrete or rock cores with a diameter no greater than Two versions can be used to complete the testing configuration: The constant normal load boundary condition may not be appropriate for problems where shearing is dilatancy controlled and the normal stress ast not constant asttm the discontinuity.

The normal loading system is complete with an adjustable low friction pressure maintainer to absorb volume changes of the specimen during qstm shearing action and to ensure a constant vertical stress. Examples of an artificial discontinuity include a rock-concrete interface or a lift line from a concrete pour.

Clearly label the sample with source, date taken, intact or sliding friction, and a short, unambiguous, identification code. ASTM D Use This test method establishes requirements and laboratory procedures for performing direct shear strength tests on rock specimens. When the normal load is large enough to completely restrain dilation, the shear mechanism consists of the shearing off of the asperities.

Therefore, the precise prediction of rock mass behavior is difficult. Report of direct shear strengths five to nine pages depending on sample type including the following:.

Relationships derived from the test data include shear strength versus normal stress and shear stress versus d55607 displacement shear stiffness. 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.

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. 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.

Reporting of test results in units other than SI shall not be regarded as nonconformance with this test method. 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. 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 adtm used. Sliding on and shearing of the asperities can occur simultaneously.

Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times.

It is beyond the scope of these test methods to consider significant digits used dd5607 analysis methods for engineering design. 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. This test method establishes requirements and laboratory procedures for performing direct shear strength tests on rock specimens. Examples of an artificial discontinuity include a rock-concrete interface or a lift line from a concrete pour.

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. 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.

Instructions Samples should be concrete or rock cores with a s5607 no greater than Results Produced Report of direct shear strengths five to nine pages depending on sample type including the following: 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.

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. 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.

Displacement and load readings shall be acquired by suitable datalogger that has to be add as accessory. For more info please refer to Releted Products below and Accessories section. The apparatus consists of a shear box designed to accept samples not larger than x mm, or alternatively cores up to mm dia.

Privacy Policy Sensors Sitemap. The test is usually conducted in the undrained state with an applied constant normal load. Therefore nominal area is used for loading purposes and calculations.
