N OTE 2—If it is not feasible to apply axial test loads to a batter pile, theresults of a test on a similar e3689-90 vertical pile generally may be used toevaluate the uplift capacity of the batter pile.
The hydraulic jack s shall be calibrated over its complete range of ram travel forincreasing and decreasing applied loads. 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. Atsm, if used as a reaction, shall be of sufficientplan dimensions to transfer the reaction loads to the soilwithout settling c3689-90 a rate that would prevent maintaining theapplied loads. If two or more reactionpiles 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.
Pile Load Testing | Common ASTMs
A number in parentheses indicates the year of last reapproval. Bearing plates on cribbing shall be set in a horizontalplane. This test method isdivided into the following sections: Apparatus for Applying Loads 4. While the procedures herein produce a relationship between appliedload and pile movement, the results may not represent long-term performance.
N OTE 1—When a pile group is subject to vertical test loads, caprotations and horizontal displacements may occur. On-line solids hold-up measurement in mineral slurries by the standard addition method. We Need Your Support. Bearing plates that supporttest beam s on timber cribbing shall aetm a side dimension notless than 1 ft 0.

Art Design Architecture Photos. Current edition approved May 25, This test method is applicable to alldeep foundation units that function in a manner similar to piles,regardless of their method of installation. Last previous edition D — N OTE 3—Plate not required atsm steel reaction pile.
The method in 4. We are always happy to assist you. If two or more reaction piles are usedat each end of the test beam sthey shall be capped with asuitable steel beam s d368-990 on the piles or on bearing plates Fig. Factors such as type and depth of reaction, soilconditions, and magnitude of loads should be considered. Aftercalibration, load cells shall not be subjected to impact loads. Standard Test Method for. N OTE 4—Unless the hydraulic jack pump is attended at all times, d3689-990 isrecommended that the jacking system be equipped with an automaticregulator to hold the load constant as pile movement occurs.
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. Technology Science Software Engineering. Calibration of load cells shall 3d689-90 eccentricloading of 1: Thank you for visiting our website and your interest in our free products and services. We are sstm website to share and download documents.
Support the ends of the test beam s withreaction piles or cribbing. Please download to get full document. List of Shortlisted Ph. All Category Directory TagCloud. If two or more jacksare d3689–90 be used to apply the test load, they shall be of the sameram diameter, connected to a common manifold and pressuregage, and operated by a single hydraulic pump.
Imperative sentencesindicate mandatory provisions. To the running of this website, we need your help to support us. Originallypublished as D — A Monte-Carlo method for portfolio optimization under partially observed stochastic volatility. All materials on our website are shared by users. The test pile s shall be cut off or built up to theproper grade as necessary to permit construction of theload-application apparatus, placement of the necessary testingand instrumentation equipment, and observations of the instru-mentation.
It does not cover the interpretationor analysis of the test results or the application of the d368-990 to foundation design. N OTE 2—Use same type reaction piles or cribbing at both ends of test beam. The occurrence of suchhorizontal movements, and the necessary reactions to resist such move-ments if they are to be prohibited, should be considered when designingand constructing the load apparatus for the group test.
Bearing plates shall beset perpendicular to the longitudinal axis of the pile. Asuperscript epsilon e indicates an editorial change since the last revision or reapproval.
