This test method isdivided into the following sections: Thank you for visiting our website and your interest in our free products and services. If two or more reaction piles are usedat each end of the test beam sthey shall be capped with asuitable steel beam s set on the piles or on bearing plates Fig.
Calibration of load cells shall include eccentricloading of 1: If two or more d36899-90 are used at each end of the test beam sthey shall becapped with a suitable steel beam s set on steel bearing platesor directly on and welded to steel reaction piles Fig. Notes and illustrations includedherein are explanatory or advisory.
Frequently Asked Questions
Asuperscript epsilon e indicates an editorial change since the last revision or reapproval. If two or more jacksare to be used to apply the test 3d689-90, they shall be of the sameram diameter, connected to a common manifold and pressuregage, and operated by a single hydraulic pump. This test method is applicable to alldeep d36889-90 units that function in a manner similar to piles,regardless of their method of installation. Cribbing, if used as a reaction, shall be of sufficientplan dimensions to transfer the reaction loads to the soilwithout settling at a rate that would prevent maintaining theapplied loads.
Apparatus for Applying Loads 4.
All materials on our website are shared by users. Technology Science Software Engineering. A number in parentheses indicates the year of last reapproval. N OTE 5—Considerations should be given to employing a dual load-measuring system pressure gage and load cell to provide as a check andas a backup in case one system malfunctions. N OTE 2—If it is not feasible to apply axial test loads to a batter pile, theresults of a test on a similar nearby aztm pile generally may be used toevaluate the uplift capacity asfm the batter pile.
The hydraulic jack s shall be calibrated over its complete range of ram travel forincreasing and decreasing applied loads.
Factors such as type and depth of reaction, soilconditions, and magnitude of loads should be considered. Whentesting a batter pile, reaction piles shall be battered in the samedirection and angle as the test pile; the test beam s shall beperpendicular to the direction of batter.

We are nonprofit website to share and download documents. N OTE 3—Plate not required for steel reaction pile.
N OTE 4—Unless the hydraulic jack pump is attended at all times, it isrecommended that the jacking system be equipped with an automaticregulator to hold the load constant as pile movement occurs. N OTE 1—When a pile group is subject to vertical test loads, caprotations and horizontal displacements may occur.
