【 摘 要 】

Complete reconstruction of the reinforced pre-stressed bridge Pavel Wonky in Pardubice was carried out in 2006. During this reconstruction specialists of the Klokner Institute made a complete revision of linear free external cables in bridge chambers, namely from the aspect of corrosion. During the ordinary visual inspection of the bearing structure of this bridge, in July 2017 [1], the SUS Pardubice staff members found out that in the places above both the pillars in the right-hand chamber of the Pavel Wonka bridge central beam in Pardubice, the blocks of deviators on the left-hand side of the chamber were deflected against the direction of stationing, towards Hradec Kralove. Some of the findings obtained during this revision are presented in this article.
