The work deals with reliability analysis of cantilever diaphragm pile wall located in spatially variable sands. The problem of serviceability limit state of the construction is considered. To precisely calculate the value of maximum wall deflection the Hardening Soil (HS) is employed as soil model. To account for soil spatial variability friction angle of the sand is modeled using anisotropic random field with specified both vertical and horizontal scale of fluctuation (SOF). The individual realizations of boundary value problem are solved using ZSoil code. The influence of horizontal SOF on the probabilistic characteristics of maximum wall deflection is tested: for assumed value of vertical SOF and few different values of horizontal SOF the probability density function of wall deflection are estimated. Based on that function the assessment of failure probability versus horizontal SOF is calculated. It is shown that in the case of diaphragm wall construction the value of horizontal SOF can significantly affect probability of serviceability failure.
