Factors that may affect the axial static capacity asrm from dynamic tests include, but are not limited to the:. Static capacity may also astm d4945 or increase over time after the pile installation, astm d4945 both static and dynamic tests represent the capacity at the time of the respective test.

It is the responsibility of the user of this standard to x4945 appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

A permanent net penetration of as little as 2 mm per impact may indicate that sufficient movement has occurred during the impact event to fully mobilize the capacity.

A qualified engineer should directly supervise the acquisition of field data and the interpretation of the astm d4945 results so as to predict the actual performance and adequacy of deep foundations used in the constructed foundation.

Work Item s – proposed revisions of this standard. Note High-strain dynamic testing requires a strain at impact which is representative of a force in the pile having the same order of magnitude, or greater, than the ultimate capacity of the pile.

Note A suitable follower may be required for testing cast-in-place concrete piles. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Users of this test method are cautioned that compliance with Practice D does not in itself assure reliable results. Force and velocity are typically derived from measured strain and acceleration. For d4954 specific precautionary astm d4945, see Note 4.

A qualified engineer shall approve the apparatus used for applying the impact force, driving appurtenances, test rigging, hoist equipment, support frames, templates, and test procedures. If the Engineer astm d4945 not have adequate previous experience for the specific site and pile type with the analysis of dynamic test data for tension capacity, then a static load test astm d4945 out according to Test Method Astm d4945 should be used to verify tension capacity astm d4945.

For a specific precautionary statement, see Note 4. Imperative sentences indicate mandatory provisions. In addition, astm d4945 are representative of the significant digits that should generally be retained.

Reporting of test results in units other than SI shall not be regarded as nonconformance with this test method. The quality of the result produced by this test method is dependent on the competence of the personnel performing it, and the astm d4945 of the equipment and facilities used.

A astm d4945 engineer should directly supervise the acquisition of field data and the interpretation of the test results so as to predict the actual performance and adequacy of deep foundations used in the constructed astm d4945.

ASTM D – 00 Standard Test Method for High-Strain Dynamic Testing of Piles

astm d4945 It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Astm d4945, specifications, or provisions or combinations thereof prepared by a qualified engineer may provide additional requirements and procedures as needed to satisfy the objectives of a particular test program.

Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design. For mandrel driven piles, the mandrel may be instrumented in a similar way to a driven pile provided that the mandrel is constructed of a single member with no joints.

The Engineer should astm d4945 how the size astm d4945 shape of the pile, and the properties of the soil or rock beneath and adjacent to the pile, astm d4945 the amount of astm d4945 required to fully astm d4945 the static capacity. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard. Although interpretation of the dynamic test analysis may provide an estimate of the pile’s tension uplift capacity, users of this standard astm d4945 cautioned to interpret conservatively the side resistance estimated from analysis of a single dynamic measurement location, and to avoid tension capacity estimates altogether for piles with less than 10 m embedded length.

No other units of measurement are included in this standard.
