<p><b>Abstract:</b> Probabilistic slope analysis extends the classical deterministic analysis by accounting for the uncertainties of input values. The probabilistic approach used in this webinar is the first-order reliability method (FORM) which includes the Hasofer-Lind index as a special case. This talk focuses on the enlightening sensitivity information provided by the design point in FORM, and insights for enhancing the load and resistance factor design (LRFD) and the Eurocode 7 (EC7) approaches. Several well-known slope cases in soils and rocks are analyzed, first deterministically then probabilistically, including the following:</p>
<ul>
<li>An underwater slope in San Francisco Bay Mud</li>
<li>An excavated slope in stiff fissured London clay</li>
<li>A Norwegian slope involving anisotropic and spatially autocorrelated soil properties</li>
<li>A zoned earth dam with a sloping clay core</li>
<li>A Hong Kong rock slope with a tension crack and a discontinuity plane</li>
<li>A rock slope with a two-block mechanism formed by discontinuities</li>
<li>3D tetrahedral wedge mechanisms in rock slopes</li>
</ul>
<p>The context-dependent sensitivities of strength and load parameters are demonstrated, with insights for LRFD and EC7.</p>
<p>This talk is similar in theme to the speaker’s paper which won the 2019 ASCE Thomas A. Middlebrooks award, but presents new cases of slope reliability analysis from his 2021 book published by the CRC Press, <span lang="EN-SG"><a href="http://www.routledge.com/9780367631390"><span style="font-size: 12.0pt; line-height: 120%; font-family: 'Times New Roman',serif;">http://www.routledge.com/9780367631390</span></a>)</span></p>
