Hydraulic Structures on Pilesby Andrew R. Blystra, A. R. Blystra & Associates Ltd, Calumet City, IL, USA,
Abstract: Many hydraulic structures built in the early 1900's were founded on piles. Today, when these structures are analyzed as 'pile-supported', the analyses often indicate that the piles are being overstressed. In the analyses, it is assumed that the entire structural load is transmitted to the piles and that the soil foundation does not contribute to the support of the structure. The pressuremeter provides a means of measuring in situ soil stresses so that the load being supported by the foundation soil can be estimated. The load supported by the soil can be subtracted from the piles and the piles re-analyzed to determine if the piles are overstressed.
