This test method is applicable aastm deep foundation units that function in a manner similar to foundation piles, regardless of their method of installation provided that they are receptive to high strain impact testing. Help Center Find new research papers in: This paper has been focused on this type of pile loading test. The side of the cap is instrumented with two strain gauges, two accelerometers and electronic theodolite target.

The capacity of the hammer should be large enough to achieve sufficient pile settlement so that the resistance of the tested pile can be fully mobilized. The comparisons of load-settlement behaviors for dynamic and static load tests, shown in Figure 5Figure 6 and Figure 7indicate that the predicted settlement from dynamic and the measured settlement from static are generally consistent to a reasonable extent as reflected by the results of towers 7 and 8.

Q Figure 6-a: This will be achieved by taking four case studies, conducted in Red Sea State in eastern Sudan. Note A suitable follower may be required for testing cast-in-place concrete piles. Essential preparations should be made before the test is carried out in the field.

The impact produces a compressive wave that travels down the shaft of the foundation. For a specific precautionary statement, see Note 5.

A schematic sketch of SIMBAT equipment and instrumentation is presented in Figure 2whereas a photograph of a complete set of the equipment is shown in Figure 3. The dynamic load pile test, which is a simple quality control test offering a considerable savings of time and cost and requires less space, xstm be used for predicting pile capacity and pile integrity under proper care and it should be calibrated by at least one static test.

It consists of estimating soil resistance and its distribution from force and velocity measurements obtained near the top of a foundation impacted by a hammer or drop weight.

ASTM D – 00 Standard Test Method for High-Strain Dynamic Testing of Piles

Q Tower 7 v4945-00 A pile cap, as an extension to the shaft head with the same diameter as the shaftshould be constructed.

This is very clear especially in the results of the pile of tower 1 project.

Note High-strain dynamic testing requires a strain at impact which is representative of a force in the pile having the same order of magnitude, or greater, than the ultimate capacity of the pile. This is Portsudan city, which is located in western coast of the Red Sea in eastern Sudan [11]. Solanki, Associte Professor, and Y. Rajagopal, Post Graduate Student, C. The length of the cap should be at least 1. A pair of strain transducers receives the signals necessary to compute force, while measurements from a pair of accelerometers are integrated to yield velocity.

Active view current version of standard. The pile design for projects should be optimized by determining the actual ultimate pile capacity, which may need to conduct pile test to failure or near to failure. This shows a reasonable agreement between the two test results. The dynamic or total reaction, Rdy is calculated for each hammer blow and plotted versus cumulative penetration for the whole set of blows.

For mandrel driven piles, the mandrel may be instrumented in a similar way to a driven pile provided that the mandrel is constructed of a single member with no joints.

Four case studies conducted in Red Sea state were taken.

The initial part of the load-settlement curves D4945-000 6: The modern change, which is considered as one of the significant beneficial changes that have been made to the system since the last Irish survey in is the introduction of theodolite to measure the pile displacement during the impact [6], [7]. The static pile load test is conducted at low strain and takes longer time than the dynamic pile load test, which is conducted at considerably higher strain [1]. Svinkin analyzed a distinctive case history presented by Briaud et al.

The formation at this area is predominantly coralline deposits consisting of completely to slightly weathered coral reef limestone that contains marine shells and fossils.

All tests were carried out on bored concrete piles.
