Abstract

Tunnel construction in water saturated soil causes changes in stress and strain of soil, which is primarily dependant on mechanical properties of soil in the tunnel construction zone. The paper presents a prediction of short-term and long-term deformations of soil, with a particular emphasis on ground surface settlements after the tunnel construction. The aforementioned predictions were made using a widely applicable numerical soil model that accurately describes the results of triaxial tests, in combination with the existing procedures for determination of soil parameters, taking at that into account natural heterogeneity of the soil as observed through heterogeneity of natural moisture of clay.
