• Số trang / Page: 16

Phạm vi áp dụng / Scope of standard

This method covers the procedure for testing a vertical or
inclined pile to determine the displacement response of the pile to
an axial compressive load pulse of a preselected target peak
force.

This test method is applicable to all deep foundation units that
function in a manner similar to piles, regardless of their method
of installation.

Two alternative procedures are provided:

Procedure A uses a combustion gas pressure apparatus to produce
the required axial compression force pulse.

Procedure B uses a cushioned drop mass apparatus to produce the
required axial compression force pulse.

All observed and calculated values shall conform to the
guidelines for significant digits and rounding established in ASTM
D6026.

The method used to specify how data are collected, calculated,
or recorded in this standard is not directly related to the
accuracy to which the data can be applied in the design or other
uses. 1.6. AASHTO takes no position respecting the validity of any
patent rights asserted in connection with any item mentioned in
this standard. Users of this standard are expressly advised that
determination of the validity of any such patent rights, and the
risk of infringement of such rights, are entirely their own
responsibility.

The values stated in SI units shall be regarded as the standard.
The inch-pound equivalents of the SI units may be approximate.

The gravitational system of inch-pound units is used when
dealing with inch-pound units. In this system, the pound (lbf)
represents a unit of force (weight), while the unit for mass is
slugs. The rationalized slug unit is not given unless dynamic (F =
ma) calculations are involved.

This standard may involve hazardous materials, operations,
and equipment. This standard does not purport to address all of the
safety concerns 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 its use. For specific hazards and
precautions, refer to Section 6.
