Significance and Use | ||||||||||||||||||
5.1 Disturbance imparted to sediments after sampling can significantly affect some geotechnical properties. Careful practices need to be followed to minimize soil fabric changes caused from handling, storing, and preparing sediment specimens for testing. 5.2 The practices presented in this
document should be used with soil that has a very soft or soft
shear strength (undrained shear strength less than 25 kPa (3.6
psi)) consistency.
5.3 These practices shall apply to
specimens of naturally formed marine soil (that may or may not be
fragile or highly sensitive) that will be used for density
determination, consolidation, permeability testing or shear
strength testing with or without stress-strain properties and
volume change measurements (see Note 3). In addition, dynamic and
cyclic testing can also be performed on the sample.
5.4 These practices apply to
fine-grained soils that do not allow the rapid drainage of pore
water. Although many of the procedures can apply to coarser-grained
soils, drainage may occur rapidly enough to warrant special
handling procedures not covered in these practices.
5.5 These practices apply primarily to soil specimens that are obtained in thin-walled or similar coring devices that produce high-quality cores or that are obtained by pushing a thin-walled tube into cores taken with another sampling device. 5.6 These practices can be used in conjunction with soils containing gas, however, more specialized procedures and equipment that are not covered in these practices have been developed for use with such materials. 1.1 These practices cover methods
for project/cruise reporting, and handling, transporting and
storing soft cohesive intact marine soil. Procedures for preparing
soil specimens for triaxial strength, and consolidation testing are
also presented.
1.2 These practices may include the handling and transporting of sediment specimens contaminated with hazardous materials and samples subject to quarantine regulations. 1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. 1.4 These practices offer a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of these practices may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project’s many unique aspects. The word “Standard” in the title means only that the document has been approved through the ASTM consensus process. 1.5 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.
