Abstract The ratio of safety margin is the bridge between deterministic design and reliability design. However, the equivalence criterion between the ratios of safety margin in terms of the factor of safety (FOS) and the reliability index is ambiguous. This paper considers the traditional and reliability-based design method at the same safety level. A general form of the FOS following lognormal distribution is adopted. It was found that the variability of FOS is affected by the normalized gradient and the coefficient of variation of random variable. The ratios of safety margin in terms of the

To detect areas with the potential for landslides, slopes are routinely subjected to stability analyses. To this end, there is a need to adopt appropriate mitigation techniques. In general, the stability of slopes with circular failure mode is defined as the factor of safety (FOS).

Geotechnical engineers have always been concerned with the stabilization of slopes. For this purpose,various methods such as retaining walls, piles, and geosynthetics may be used to increase the safety factor of slopes prone to failure. The application of stone columns may also be another potential alternative for slope stabilization. Such columns have normally been used for cohesive soil improvement. Most slope analysis and design is based on deterministic approach i.e a set of single valued design parameter are adopted and a set of single valued factor of safety (FOS) is determined. Usually

Abstract:

Since geosynthetic interfaces often serve as a weak plane on which sliding may occur, shear strengths of these interfaces need to be carefully assessed. In this case study, geosynthetic and soil samples were exhumed from the base and side slope of a constructed facility to generate site specific data. The importance of using representative materials and performing the shear interface testing under conditions similar to those expected in the field are discussed. Once the test data was available, they were used in a stability analysis software package to determine the Factor of Safety (FoS) of t

Slope dynamic factor of safety (FOS) under earthquake was calculated based on time history analysis method and compared with acceleration time history to analyze correspondence between them. In view of the fact that earthquake is a dynamic process, this paper proposed that three respects can be considered to analyze the slope stability rather than adopting a single FOS value. Firstly, the variation trend of the FOS time history can be combined with the forces on key points to analyze slope stability. Secondly, the displacement and stress vector fields can be adopted to evaluate the final slope

Bacterial biofilms are highly resistant to common antibacterial treatments, and several physiological explanations have been offered to explain the recalcitrant nature of bacterial biofilms. Herein, a biophysical aspect of biofilm recalcitrance is being reported on. While engineering structures are often overdesigned with a factor of safety (FOS) usually under 10, experimental measurements of biofilm cohesive strength suggest that the FOS is on the order of thousands. In other words, bacterial biofilms appear to be designed to withstand extreme forces rather than typical or average loads. In s

In this paper, it proves that the necessary and sufficient condition for the potential sliding body reaching the ultimate limit equilibrium state is that the summation of shear stresses along the sliding surface equals to that of resistant shear strength. Based on the rigorous theory analyses and derivations, it is clearly shown that the definition of factor of safety (FOS) in the slip surface stress method (SSSM) is irrelevant with the shape of slip surface. Thus, the authors demonstrate that the FOS of noncircular slip surface can also be defined as the ratio of the sum of resistant sliding
