Abstract
The largest bridge of the motorway ring road of Wroclaw is a cable stayed bridge over the Odra river near Rędzin. Due to hydrogeological conditions of the ground it was not convenient to use standard bored piles of high length. Instead shorter piles were applied with additional improvement by cement injections at the pile toes. This decision was possible by extending ground investigation program and application of numerical modeling of the soil-structure interaction with nonstandard material models of the overconsolidated clayey deposits. Sufficient stiffness and bearing capacity of piles was approved by field tests. Overall performance of the foundation was monitored during construction and after completion of the bridge. Comparison of settlements predicted during design and obtained in the monitoring is presented and discussed.
