ASTM D pile integrity testing._百度文库
A contingency plan should be formed that allows the engineer to possibly perform further tests or dictate pile repair ashm replacement prior to 58822 integrity testing, in case a serious defect is indicated. The method works best on solid concrete sections, and has limited application to unfilled steel pipe piles, H piles, or steel sheet piles. For piles with diameters larger than mm, attach the accelerometer at a minimum of three locations so that an integrity evaluation near the pile head may be made for each localized section of pile.
The method is generally not suitable for testing steel sheet, H-section or un? The apparatus shall allow for a permanent graphical output of the records. A typical schematic arrangement for this apparatus is illustrated in Fig. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
The hammer must be tuned such that the fourrier transform of the measured force shall have a smooth spectrum, without any local peaks.
Users of this test method are cautioned that compliance with Practice D does not in itself assure reliable results. These limitations must be understood and taken into FIG.
ASTM D 5882-16 Compliance Statement
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. The apparatus shall include a graphic display of velocity and force optionaland a data storage capability for retrieving records for further analysis. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
Alternately, the pile head force can be measured as well. Asrm one applies the results obtained using this standard is beyond its scope. Comparison of 582 from several piles from the site with similar construction is recommended to assess the typical response with the same ampli?
The accelerometer s should be placed at or near the pile head and xstm have their sensitive axis parallel with the pile axis. The motion during the impact event ashm normalized usually and is associated with the pile head.
Set up the apparatus for recording, reducing, and displaying data so that it is operational and the force and velocity signals are zeroed. Visual interpretation may be qualitative and asmt relative to other tested piles and a matter of proper engineering judgment. The apparatus shall be capable of transferring all data to a permanent storage medium. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations astk to use.
Users of this test method are cautioned that compliance with Practice D does not in itself assure reliable results. This standard does not purport to address all of the safety concerns, if any, associated with its use. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard.
This test method astj applicable to long structural elements that function in a manner similar to any deep foundation units such as driven piles, augeured piles, or drilled shaftsregardless of their method of installation provided that they are receptive to low strain impact testing.

When digitizing, the sample frequency, therefore, shall be at least 30 Hz each for the motion sensor and x optional instrumented hammer, if used. The apparatus shall be able to apply increasing intensity ampli? Attach the motion sensor? A superscript epsilon e indicates an editorial change since the last revision or reapproval.
This test method is applicable to long structural elements that function in a manner similar to foundation piles, regardless of their method of installation provided that they are receptive to low strain impact testing. If 588 the individual impacts are recorded, ensure that the apparatus for recording, reducing, and displaying data is capable of averaging up to 10 individual records.
No other units of measurement are included in this standard. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
