Discontinuities may be open, partially or completely healed or filled that is, clay fillings and gouge. Relationships derived from the test data include shear strength versus normal stress and shear stress versus shear displacement shear stiffness.

Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times. Users of this standard are cautioned that compliance with Practice D does not in itself assure reliable results. 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.

This apparatus was originally developed at Imperial college, London, by Professor E. 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.

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. Reporting of test results in units other than SI asgm not be regarded as nonconformance with this test method.

Reliable results depend on many factors, Practice D provides a means of evaluating some of those factors. Report of direct shear strengths five asgm nine pages depending on sample type including the following:.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not dd5607 as part of the standard. Samples should be sealed in a plastic wrap inside their shipping container, protected against air, moisture, and direct sunlight.

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. The quality of the result produced by sstm standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Relationships derived from the test data include shear strength versus normal stress and shear stress versus shear displacement shear wstm.

Two versions are available:.

However, a clean, open discontinuity may be free draining, and, therefore, a test on a clean, open discontinuity could dd5607 considered a drained test. Sliding on and shearing of the asperities can occur simultaneously. 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. Therefore, the precise prediction of rock mass behavior is difficult.

Two versions can be used to complete the testing configuration: When the normal load is large enough to completely restrain dilation, the shear mechanism consists of the shearing off of the asperities.

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. Therefore nominal area is astmm for loading purposes and calculations.

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.
