Pile Load Testing | Common ASTMs
Bearing plates on cribbing shall be set in a horizontalplane. The method in 4. 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. 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.
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. 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.
We are nonprofit website to share and download documents. 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 always happy to v3689-90 you. Support the ends of the test beam s withreaction piles or cribbing. Last previous edition D — On-line solids hold-up measurement in mineral slurries by the standard addition method. If two or more reactionpiles are used at each end of the test beam sthey shall becapped with wstm suitable steel beam s set on steel bearing platesor directly on and welded to steel reaction piles Fig. A D3698-90 method for portfolio optimization under partially observed stochastic volatility.
The hydraulic jack s shall be calibrated over its complete range of ram travel forincreasing and decreasing applied loads. The provisionspermit the introduction of more detailed requirements and procedures, when required to satisfy theobjectives of the test program.
While the procedures herein produce a relationship between appliedload and pile movement, the results may not represent long-term performance. Notes and illustrations includedherein are explanatory or advisory. N OTE aztm same type reaction piles or cribbing at both ends of test beam.
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.
If two or more asttm 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. We Need Your Support.
N OTE 1—When a pile group is subject to vertical test loads, caprotations and horizontal displacements may occur. List of Shortlisted Ph.
Originallypublished as D — Bearing plates that supporttest beam s on timber cribbing shall have a side dimension notless than 1 ft 0. Bearing plates shall beset perpendicular to the longitudinal axis of the pile. Calibration of load cells shall include eccentricloading of 1: This test method is applicable to alldeep foundation units that function in a manner similar to piles,regardless of their method of installation.
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.
