Summary:
An extensive instrumentation program was carried out over a 6-month period on a 50-ft (15.2-m) deep braced cut in dense sand. The temporary bracing system consisted of interlocking steel sheet piles (Larssen type IIIN), wales, and struts from wide-flange steel sections. The soil consisted of fine, uniformly graded sand with varying relative densities from medium to very dense. The loads of the struts on each side of the center bay for three strut levels were obtained by measuring the strains in the struts with a mechanical dial gage over an 8-in. (20.3-cm) gage length. The reliability and precision of these measurements are discussed.
