Abstract

On the use of trenches and walls on the control of ground transmitted railway vibrations J. Mateo" & E. Alarcon^ o^T.^. de ingemeros AWnd, ABSTRACT An actual case of an underground railway in the neighbourhood of habitation buildings has been analyzed. The study has been based on a twodimensional BEM model including a tunnel and a typical building. The soil properties were obtained using geophysical techniques. After a sensitivity study, the model has been simplyfied and validated by comparison with "in situ" measurements. Using this simplyfied model, a parametric study has been done including trenches and walls of different materials and different depths at two different distances from the tunnel. The reductions obtained with the different solutions can then be compared. 1. PROBLEM DESCRIPTION An increasing number of litigation between building owners and railway companies is been registered recently due on the one hand to the city developments and the
