    Abstract
  • Marine soils have significant non-uniformity due to complex geological factors during the formation process, which can impact the safety and serviceability of marine geotechnical structures. Accurately identifying soil layers and determining soil properties are crucial for assessing foundation bearing capacity, predicting deformations, and designing marine geotechnical structures. A soil profile stratification method considering uncertainty was developed based on random field theory. By incorporating spatial correlations between soil layers, the probabilities of each soil element belonging to specific soil categories were estimated and two-dimensional soil stratification was achieved through Monte Carlo sampling. The influence of depth factors and the number of boreholes on the uncertainty of stratification results was analyzed. The results demonstrated that this approach can achieve two-dimensional soil stratification within the coverage range of limited borehole data. Reduction in the number of boreholes could increase the uncertainty of stratification results.
