Dynamic loads for high-strain dynamic pile testing

摘要

The main purpose of high strain dynamic pile testing is the determination of the pile capacity at the time of testing. It is important to know the magnitude of the applied dynamic load in high-strain testing. Nevertheless, there are no widely accepted requirements for producing or measuring the load except that the pile capacity must be fully mobilized during dynamic testing. A simplified procedure to calculate short-duration impact loads is suggested that takes into consideration pile capacity and parameters when performing high-strain dynamic pile tests. Comments are also included regarding the current CAPWAP, TNOWAVE, and SIMBAT methods for determination of pile capacity by high-strain dynamic pile testing.
