In addition, they are representative of the significant digits that generally should be retained. It includes procedures for both intact asm strength and sliding friction tests which can be performed on specimens that are homogeneous, or have planes of weakness, including natural or artificial discontinuities.

Only one discontinuity per specimen can be tested. Discontinuities may be open, partially or completely healed or filled that is, clay fillings and gouge. Active view current version of standard.

Discontinuities may be open, partially or completely healed or filled that is, clay fillings and gouge. 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.

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. It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering design.

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

Active Risk Management

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. 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. Results Produced Report of direct shear strengths five to nine pages depending on sample type including the following: 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 axtm lower halves of the specimen during testing.

Samples should be sealed in a plastic wrap inside their shipping container, protected against air, moisture, and direct sunlight.

Print and complete the following order form. The actual contact areas during testing change, but the actual total contact surface is unmeasurable. Reliable results depend on many factors, Practice D provides a means of evaluating some of those factors.

The values given in parentheses are mathematical conversions to inch-pound units, which are provided for information only and are not considered standard. Examples of an artificial discontinuity include a rock-concrete interface or a lift line from a concrete pour. Report of direct shear strengths five to nine pages depending on sample type including the following:.

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

ASTM D Use This test method establishes requirements and laboratory procedures for performing direct shear strength tests on rock specimens. The test is usually conducted in the undrained state with an applied constant normal load.

Relationships derived from the test data include shear strength aastm normal stress and shear stress versus shear displacement shear stiffness. Users of this standard are cautioned that compliance with Practice D does not in itself assure reliable results. Therefore nominal area is used for loading purposes and calculations. The apparatus aatm of a shear box designed to accept samples not larger than x mm, or alternatively cores up to mm dia.

The actual contact areas during testing change, but the actual total contact surface is unmeasurable. Pervasive discontinuities joints, bedding planes, shear zones, fault axtm, 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.

Two set of cables are required. It is a simple and practical method of determining the strength and slope stability of rock, both in the field and in the laboratory.
