The paper presents a numerical analysis of the impact of an unsecured excavation on an underground pipeline in selected soil conditions. The research was inspired by a real-life failure of a water pipeline which was caused by a nearby unsecured excavation (Sikora et al. 2015). The failure was triggered by displacement of soil mass in the vicinity of the pipeline. The study conducted in the framework of Finite Element Method is focused on analyzing different soil conditions and pipe rigidity combinations and calculating the resulting displacements. The FEM parametric study aims at investigation of the soil model parameters sensitivity on the possible magnitude of horizontal and vertical deformations. The research and analysis can be incorporated into recommendations for engineers performing earthworks in urban areas.
