  • Hilfiker retaining walls with full height castinplace panels
    Hilfiker retaining walls with full height cast-in-place panels
    Osseiran, Abdallah H.
    1998-02-01 | PDF
    Construction of retaining walls utilizing full height panels introduces a degree of indeterminacy to the structure. The ability to effectively analyze the internal behavior of such systems, and limited field performance, qualifies them as appropriate to the experimental category. Arizona recently utilized this technique for building three permanent ...
