This paper deals with the probabilistic modelling of a triple-anchored diaphragm wall. The analysis is carried out using random finite element method based on N=1000 Monte Carlo simulations. Single spatially variable soil layer described by two random fields modelling normalized CPTu parameters Qtn and Fr is assumed. The probability distribution, cross-correlation coefficient and vertical SOF for both random fields are identified based on CPTu tests of normally consolidated sand from central part of Poland. The Hardening Soil-Brick model is adopted for the soil medium and its parameters are derived based on local Qtn and Fr values. The paper presents the obtained probability characteristics of the results, namely: maximum displacement of the wall, maximum bending moment in the wall and value of force in the upper anchor.
