Degradation and corrosive
processes of structures cannot be generally prevented. They are manifested by
the structures’
ageing. Experimental monitoring and investigation of Charles
Bridge has shown exceptional importance of non-force impacts and effects acting
on structures. These impacts and effects due to namely physical, chemical and
microbial processes are a major cause of gradual deterioration and ageing of
structures. From the point of view of
preservation of prominent
structural and
cultural monuments, it is necessary to study these processes, their causes and
mutual connections.
