History
The predecessor of this center was a hydraulic experiment station that opened in 1979 on a site of approximately one hectare on the outskirts of Maebashi City, Gunma Prefecture.
-
1984 (Showa 59)
December
Moved to Tsukuba City, Ibaraki Prefecture and established the "Tsukuba Experimental Site" on a site of approximately 2 hectares.
-
1987 (Showa 62)
October
The total site area was expanded to approximately 4 hectares to accommodate larger-scale experiments.
-
1992 (Heisei 4)
April
Completion of office building, 2-story steel-framed building, total floor area 660m²
-
2001 (Heisei 13)
August
Constructed a laboratory capable of carrying out a variety of experiments, tests, and technological development, opened an environmental analysis room, and changed the name to "Tsukuba Technology Research Center."
Main Achievements
Tokaido Main Line Fujikawa Bridge
On August 20, 1982, heavy rains caused by Typhoon No. 10 caused the fourth pier of the Tokaido Main Line Fuji River Bridge's outbound line toppled, washing away two truss girders. The flood flow velocity reached 8m/s, and it was estimated that the flowing water acted on the overturned pier at an angle of approximately 10 degrees. These estimates were verified by hydraulic model experiment.

Great East Japan Earthquake: "Consideration of Resilient Coastal Embankments"
Learning from the Tohoku Pacific Ocean Earthquake, it became necessary to develop and improve coastal embankment structures that would be able to maintain their effectiveness even when tsunami heights exceeded the heights they were designed for. Hydraulic model experiment were conducted to examine resilient coastal embankment structures.
