ABSTRACT
The structural health
monitoring of a dam is important for maintaining the safe operation and
longevity of the dam system. The structural health of a large dam can be
monitored from the measured static deformation. This paper presents an
investigation of the parameter variations of the identified model of the
measured long-term static deformation for the structural health monitoring of
Fui-Tsui Dam, which is located in a very active seismic zone of Taiwan. The
measured static deformation is characterized as a function of the measured
physical parameters, including the effects of hydrostatic pressure and
temperature variation. The identified parameters, associated with the effects
of hydrostatic pressure and temperature variation, change with environmental
factors, such as flooding, earthquake and foundation change.
