On the project

Description in English
A long-term monitoring as well as laboratory and theoretical analyses show that a lot of defects appearing in the structure and individual stone blocks are mostly caused by the effects and influence of temperature and moisture (due to different humidity,temperature and different dilatometric features) which are putting the structure of Charles Bridge under variable intensity stress. This stress is due to mutual interaction of individual parts of the bridge with different primary volume changes. The rising intensity of physical, chemical and microbiological corrosion as well as degradation processes of the stone walls of bridge vaults, piers and supporting walls is very alarming. Reliability assessment of rehabilitation and reconstruction measures requires a detailed analysis of the interaction of the external environment and degradation processes in time, including and taking into account namely the specificities of repeated and cyclic temperature and moisture effects.
