“…Since the uncertainty of soil properties is inevitable in seismic slope stability analysis, the traditional deterministic methods such as pseudo-static (Macedo and Candia, 2020) and pseudo-dynamic (Yang et al, 2023) limit equilibrium methods often require a redundant factor of safety to compensate the potential uncertainties in soil properties leading to conservative design or reinforcement. Therefore, the probabilistic methods have been widely used (Zhou et al, 2023;Huang et al, 2022;Alamanis and Dakoulas, 2022;Liao and Ji, 2021;Jiang et al, 2014Jiang et al, , 2018Du et al, 2018b;Veylon et al, 2017;SongRodriguez-Marek, 2015;Cho, 2007;El-Ramly et al, 2002) and have become favorable tools to solve the problem of uncertainty and randomness in geotechnical engineering (Tang et al, 2012;Wang, 2012;Wang et al, 2011;Zevgolis and Bourdeau, 2010;Low and Tang, 2007;Griffiths and Fenton, 2004). Reliability analysis methods can be divided into two categories.…”

PurposeThis paper aims to develop an efficient algorithm combining straightforward response surface functions with Monte Carlo simulation to conduct seismic reliability analysis in a systematical way.Design/methodology/approachThe representative slip surfaces are identified and based on to calibrate multiple response surface functions with acceptable accuracy. The calibrated response surfaces are used to determine the yield acceleration in Newmark sliding displacement analysis. Then, the displacement-based limit state function is adopted to conduct seismic reliability analysis.FindingsThe calibrated response surface functions have fairly good accuracy in predicting the yield acceleration in Newmark sliding displacement analysis. The seismic reliability is influenced by such factors as PGA, spatial variability and threshold value. The proposed methodology serves as an effective tool for geotechnical practitioners.Originality/valueThe multiple sources of a seismic slope response can be effectively determined using the multiple response surface functions, which are easily implemented within geotechnical engineering.
