The highlight of Kamishiiba Dam
First Japanese large-scale arch-type dam
Shortening for term of works and reduction of material realized with thing to use strong bedrock of both sides, and to impute the water pressure to sidewall by arch action, and to support whereas arch-type dam was dam representing form of arc which did arrangement in direction of reservoir, and conventional gravity type dam supported the water pressure with weight of dam itself. We mobilized total cost of construction 14.9 billion yen, total number of man-days 5 million and we started construction in 1950 and were completed on May 26, 1955. Damage caused by typhoon No.12 of September, 1954 was serious, and upper Shiiba power station was damaged, and construction plants were washed a lot away, too. However, dam main unit proved the durability for flood of arch-type dam really unhurt.
