Title: Effect of resonance compaction method on the bearing capacity considering geotechnical spatial variability characteristics
Abstract: Using the resonance compaction method (RCM) (Gong, Zhao, C. Hsein Juang, et al. 2020), energy is transferred to non-cohesive soil by the vibratory probe. Consequently, soil spatial changes occur and liquefaction is reduced. It should be noted, however, that the spatial variability of soil is determined by the deposition process. Therefore, it is worthwhile to investigate whether and what changes in the spatial variability of the soil will occur if the soil is treated with the RCM. And how the change in spatial variability affects the bearing capacity of the soil. The random field theory was used in this study to characterize the spatial variability of soils. A Bayesian framework was used for the solution of a random field model for the non-cohesive soils before and after RCM. This involves determining the random field correlation function and determining the model parameters. Furthermore, the random finite element method (RFEM) incorporating the random field theory (RFT) and the Monte Carlo simulation (MCS) were used to assess the effects of changes in the spatial variability of the soil on the bearing capacity before and after treatment. According to the results, the RCM could not only improve the soil's bearing capacity, but also reduce its spatial variability.
