Although this method considers different loading conditions by using suitable combinations of design values, it is still based on direct comparison of the available shear strength with the mobilized stresses. In the present paper, various factoring strategies (in addition to the traditional one with respect to shear strength of soils) are integrated into a limit-state method framework. Eurocode 7 has been chosen for this purpose. The whole procedure aims at giving a more comprehensive insight into the design of slopes and the sensitivity of safety level of slopes to the various parameters. In addition, the proposed methodology, as shown, may result in a safety level of slopes significantly lower than the respective one obtained using the limit-state method in its traditional form. As man-made slopes that conform to design standards often fail in practice, even though conservative input values are used, these failures must be treated with more skepticism by practitioners adopting supplementary design practices such the one presented herein.]]> Sat 24 Mar 2018 07:55:56 AEDT ]]> Rheological characteristics of weak rock mass and effects on the long-term stability of slopes https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:19204 Sat 24 Mar 2018 07:55:00 AEDT ]]> Stability charts for rock slopes based on the Hoek-Brown failure criterion https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:5325 Sat 24 Mar 2018 07:45:57 AEDT ]]> Poro-mechanical coupling influences on potential for rainfall-induced shallow landslides in unsaturated soils https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:29642 Sat 24 Mar 2018 07:41:54 AEDT ]]> Slope stability analysis by means of finite element limit analysis and finite element strength reduction techniques: part I: numerical studies considering non-associated plasticity https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26700 Sat 24 Mar 2018 07:26:24 AEDT ]]> On the efficient estimation of small failure probability in slopes https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:31039 pf) is small, the direct Monte Carlo simulation requires a large number of simulations. Subset simulation is one of most efficient variance reduction techniques for the simulation of small pf. It has been recently proposed to use subset simulation instead of direct Monte Carlo simulation in RFEM. It is noted, however, that subset simulation requires calculation of the factor of safety (FS), while direct Monte Carlo requires only the examination of failure or non-failure. The search for the FS in RFEM could be a tedious task. For example, the search for the FS of slope stability by the strength reduction method (SRM) usually requires much more computational time than a failure or non-failure checking. In this paper, the subset simulation is combined with RFEM, but the need for the search of FS is eliminated. The value of yield function in an elastoplastic finite element analysis is used to measure the safety margin instead of the FS. Numerical experiments show that the proposed approach gives the same level of accuracy as the traditional subset simulation based on FS, but the computational time is significantly reduced. Although only examples of slope stability are given, the proposed approach will generally work for other types of geotechnical applications.]]> Sat 24 Mar 2018 07:25:48 AEDT ]]> Identification of representative slip surfaces for reliability analysis of soil slopes based on shear strength reduction https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30515 Sat 24 Mar 2018 07:25:07 AEDT ]]> Cracking, stability and slope reinforcement analysis relating to the Jinping dam based on a geomechanical model test https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:25159 Sat 24 Mar 2018 07:14:29 AEDT ]]> Slope stability analysis by means of finite element limit analysis and finite element strength reduction techniques.

Comparison of a strength reduction technique with rigorous finite element limit analysis confirms that the factors of safety (FoS) obtained are very similar for associated plasticity, an intrinsic assumption of limit analysis. For non-associated plasticity, a modified version of the so-called Davis approach has been applied because it has been shown that the original formulation proposed by Davis works well when the FoS is defined in terms of loads but is not appropriate when the FoS is defined in terms of soil strength. The results show that, with the modified Davis parameter, both strength reduction finite element analyses and finite element limit analyses provide very similar factors of safety. The key advantage of limit analysis, however, is that the value of the FoS can be bracketed from above and below with upper and lower bound calculations.]]> Sat 24 Mar 2018 07:12:35 AEDT ]]> Three-Dimensional Discrete Element Analysis of Jointed Rock Slope Stability Based on the Universal Elliptical Disc Model https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53889 Mon 22 Jan 2024 14:49:35 AEDT ]]> Stability of earth slopes.
