Factors such as type and depth of reaction, soilconditions, and magnitude of loads should be considered. A Monte-Carlo method for portfolio optimization under partially observed stochastic volatility. Thank you for visiting our website and your interest in our free products and services.
We Need Your Support. 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 vertical pile generally may be used toevaluate the uplift capacity of the batter pile.
Current edition approved May 25, N OTE 3—Plate not required for steel reaction pile. N OTE 1—When a pile group is subject to vertical test loads, caprotations and horizontal displacements may occur. Art Design Architecture Photos.
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. Standard Test Method for. 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.
If two or more jacksare to 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. 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.
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. If you have any questions about copyright issues, please report us to resolve them. All Category Directory TagCloud. Asuperscript epsilon e indicates an editorial change since the last revision or reapproval.
On-line solids hold-up measurement in mineral slurries by the standard addition method. While the procedures herein produce a relationship between appliedload and pile movement, the results may not represent long-term performance.

Bearing plates that supporttest beam s on timber cribbing shall have a side dimension notless than 1 ft 0. This test method is applicable to alldeep foundation units that function in a manner similar to piles,regardless of their method of installation.
Support the ends of the test beam s withreaction piles or cribbing. Bearing plates on cribbing shall be set in a horizontalplane. The provisionspermit the introduction of more detailed requirements and procedures, when required to satisfy theobjectives of the test program.
The method in 4. Aftercalibration, load cells shall not be subjected to impact loads.
If two or more reactionpiles are used at each end of the d33689-90 beam sthey shall becapped with a suitable steel beam s set on steel bearing platesor directly on and welded to steel reaction piles Fig. Apparatus for Applying Loads 4. Calibration of load cells shall include eccentricloading of 1: All astmm on our website are shared by users.
It does not cover the interpretationor analysis of the test results or the application of the testresults to foundation design. Technology Science Software Engineering.
Pile Load Testing | Common ASTMs
N OTE 5—Considerations should be given to employing a dual load-measuring system asttm gage and load cell to provide as a check andas a backup in case one system malfunctions. This test method isdivided into the following sections: A number in parentheses indicates the year of last reapproval. To the running of this website, we need your help to support us.
Bearing plates shall beset perpendicular to the longitudinal axis of the pile. N OTE 2—Use same type reaction piles or cribbing at both ends of test beam.
The hydraulic jack s shall be calibrated over its complete range of ram travel forincreasing and decreasing applied loads. Last previous edition D — Originallypublished as D — List of Shortlisted Ph. 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.
