    Abstract

    This two-part set of papers reports some recent experiences in the design of jet-grouted piles (under predominantly lateral load) when their intended use is
    primarily structural, as is certainly the case when reinforcing steel is present. Although unusual, a number of such design solutions have been documented – several of them recent and applied to major structures. In the absence of specialist rules for the design of jet-grouted piles with steel reinforcement, codes of practice for reinforced concrete (RC) are usually adopted and
    applied as discussed in this paper. However, certain important differences between concrete and jet-grouted soil (fully discussed in the companion paper) must be clearly understood and allowed for by designers with the
    result that analysis and design from first principles should be undertaken instead of relying automatically on RC codes of practice. This use of first principles must be combined with a refined construction method to improve the accuracy of construction if the designer is to utilise the potential benefits of the system.
