Organization: ASTM
Publication Date: 10 January 2002
Status: inactive
Page Count: 7
ICS Code (Earthworks. Excavations. Foundation construction. Underground works): 93.020
scope:

This test method is used to determine the in situ modulus of deformation of rock mass by subjecting a test chamber of circular cross section to uniformly distributed radial loading; the consequent rock displacements are measured, from which elastic or deformation moduli may be calculated. The anisotropic deformability of the rock can also be measured and information on time-dependent deformation may be obtained.

This test method is based upon the procedures developed by the U.S. Bureau of Reclamation featuring long extensometers (1)2. An alternative procedure is also available and is based on a reference bar (2).

Application of the test results is beyond the scope of this test method, but may be an integral part of some testing programs.

The values stated in inch-pound units are to be regarded as the standard.

This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.

*A Summary of Changes section appears at the end of this standard.
