Instrumentation for Measurement of Axial Load in Drilled Shafts.

摘要

A major problem in the full-scale load test of drilled shafts is defining the load distribution along the length of the shaft. Defining the load distribution requires the measurement of load in the shaft at various points along the shaft's length. One phase of the drilled shaft test being conducted by The University of Texas involves developing a suitable instrumentation system for measurement of load in drilled shafts. To date a total of four shafts have been instrumented with a combination of five different instrumentation systems. Three of the five systems were designed and constructed at The University of Texas at Austin. As the result of the instrumentation and subsequent testing of these four drilled shafts,an electrical instrumentation system developed at The University of Texas has been adopted as the instrumentation system to be used in the instrumentation of future shafts of the project.
