Deformation of Profiles in Neogen Marls in the Course of Tunnel Construction at Close Distance

摘要

In this work are shown the results of measurements of profile convergence for town zone railroad tunnel which is under construction at Karaburma in Beograd and existing tunnel Banat, with which the new tunnel should be connected. The construction technology elements are analyzed concerning the influences to the size of convergence of the profile of the tunnel under construction, as well as the influences of this construction to the neighboring existing tunnel which was all the time in traffic operation.
