Evolution of Top of Pile Measurement Techniques in Deep Foundation Static Load Testing
Article Type: Technical Note
Sinnreich, J. & Simpson, R.
Abstract
Ensuring the accuracy of collected data during deep foundation static load tests is of paramount importance. Typically, pile head displacements are measured relative to a purpose-built reference system, which is assumed to be fixed. This study presents a simplified error analysis of this assumption, illustrates the potential magnitude of these errors, and proposes an improved method of pile head displacement monitoring."
