Evolution of Top of Pile Measurement Techniques in Deep Foundation Static Load Testing (Vol. 3 No. 2) (TECHNICAL NOTE)

Jon Sinnreich; Robert C. Simpson

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."
