Random Finite Element Analysis and Random Factor response Mechanism for Geocell-reinforced Soil Retaining Walls
Published 2025-01-01“…Correspondingly, the discretization of vertical settlement shows a similar reduction trend. The random field analysis method established in this study is able to capture the uncertainty of engineering behavior more comprehensively and provides a more reliable prediction tool for the design of reinforced soil structures, which helps to optimize the engineering safety reserve and reduce the risk associated with uncertainty.ConclusionsThe results show that: the random envelope range of horizontal displacement and vertical settlement of reinforced earth retaining wall decreases with the decrease of height of reinforced earth retaining wall (points H-1~H-5) and away from the retaining wall face (points V-1~V-7); the decrease of fluctuation range or coefficient of variation reduces the dispersion of the calculation results, in which the cumulative distribution probability of the parameter <italic>φ</italic><sub>0</sub> is closer to the random distribution results, while the parameters <italic>n</italic> and <italic>P</italic><sub>Mt</sub> are with the deterministic results The effect of vertical fluctuation range on the failure probability is more significant than that of horizontal direction. …”
