The major considerations in the interpretation of high strain dynamic pile tests (HSDPT) can be categorised into four major sections as follows: Data Input Checking. Data Quality Checking. Data Interpretation (CAPWAP) Applications and Limitations. 13.2. DATA INPUT CHECKING.
With the structural stress-strain behaviour of the pile body, one can measure the change of axial strain of pile section, then interpret the philosophical stress within the pile section to deduce the axial forces at both ends of pile segment to understand how the load transfer mechanism behaves with the pile segment.

Mar 15, 2024 · High Strain Dynamic Testing (HSDT) is a method used in geotechnical engineering to evaluate the dynamic properties of soils and rocks. It involves subjecting the ground to a rapidly applied load or stress, typically using techniques such as the drop-weight or dynamic penetration testing.
Therefore, geotechnical judgment based upon knowledge of the local soil conditions and deep foundation installation practice should be used to modify this sample specification to address the requirements of a specific project.
ABSTRACT. High strain PDA testing has become common for verification of capacity of both driven and bored piles. It also investigates other aspects of the installation of driven piles such as hammer efficiency and driving stresses. The high benefit of dynamic test results for the relatively low costs of the tests has resulted in widespread use.
The calibrating strain gauges will be used to assess the actual pile stiffness, AE values for interpretation. If casing is used to build up the pile head, it is advisable to remove the steel casing before casting or place the 1st level of strain gauges below the casing to avoid interaction from the confining force of the steel casing.
