    Reliability-based design is relatively well established in structural design. Its use is less mature in geotechnical design, but there is a steady progression towards reliability-based design as seen in the inclusion of a new Annex D on "Reliability of Geotechnical Structures" in the third edition of ISO 2394. Reliability-based design can be viewed as a simplified form of risk-based design where different consequences of failure are implicitly covered by the adoption of different target reliability indices. Explicit risk management methodologies are required for large geotechnical systems where soil and loading conditions are too varied to be conveniently slotted into a few reliability classes (typically three) and an associated simple discrete tier of target reliability indices.


    Example of reliability-based shallow foundation design

    SORM analysis on the foundation of FORM results for a rock slope

    Probabilistic analyses of a slope failure in San Francisco Bay mud

    Reliability analysis of a Norwegian slope accounting for spatial autocorrelation

    System FORM reliability analysis of a soil slope with two equally likely failure modes

    Multicriteria RBD of a laterally loaded pile in spatially autocorrelated clay

    FORM design of an anchored sheet pile wall

    Reliability analysis of roof wedges and rockbolt forces in tunnels

    Probabilistic settlement analysis of a Hong Kong trial embankment on soft clay

    Coupling of stand-alone deterministic program and spreadsheetautomated reliability procedures via response surface or similar methods
