Quest
Structures has planned and conducted experimental investigations
to study dam-water-foundation interaction effects and to assess
the actual field performance of dams for more than two decades.
Our engineers have undertaken in-situ testing of concrete dams,
providing excitation with shakers and explosive charges buried in
the foundation rock or detonated in the reservoir water. We have
used measured responses from such excitations to establish dynamic
characteristics of the dam, foundation rock, and the impounded water.
We have also used field measurements to verify the accuracy of analysis
techniques and modeling assumptions commonly employed in design
and evaluation of concrete dams.
The
results of such research have led to improved understanding of the
dam-water-foundation interaction effects and more realistic estimate
of the dam response to earthquake loading. We have participated
in experimental studies of Xiang Hong Dian and Quan Shui Arch Dams
in China, and have conducted field measurements at Monticello Dam
in California followed by experiments at Dongjiang and Longyangxia
Dams in China.
