GEOSTATISTICAL METHOD FOR ANALYSING SOIL DISPLACEMENT FROM UNDERGROUND URBAN CONSTRUCTION
The aim of this study was to assess the influence of uncertainties related to soil variability in the numerical modelling of settlements caused by underground work. Based on a large number of in situ tests, a geostatistical method, kriging, applied to the stratigraphy of the subsurface was justified and used in order to determine the mean position of the soil layers and their estimation variances. In a first stage, the influence of the uncertainty in the soil stratigraphy on the calculated surface settlements was analysed. In a second stage, a stochastic finite element method was used to introduce the influence of uncertainty in the soil mechanical parameters on the predicted surface settlements. (A)
