Zajištění portálové jámy tunelu Blanka v Praze pilotovými stěnami

Abstract

The aim of this diploma thesis was the shoring structures of tunnel´s portal pit. This tunnel is belong to Prague urban ring called „Blanka“. This thesis was concerned especially the Myslbekova pit. The selection of technologies was limited by the claim to find the most effective solving for security of the Myslbekova portal pit. There was used the FEM for simulation of realized solving in this portal pit. The results obtained by this method were compared with actual values significances on construction. The first part is based on describing the security project of the trench foundation pit. Next part of this thesis bring information about confrontation the rated values significances and values significances measured in site. Finally, I was appended some own notices from bulding-up of Myslbekova portal pit.
