日本用碾压混凝土成功地建起了大川坝和岛地川坝之后,于1980年5～10月利用新中野坝加高的机会,在该坝下游消力墩基础施工中做了新的实践研究,并根据以上三个坝的施工经验,决定玉川坝亦采用碾压混凝土筑坝技术。
After Japan successfully built Dachuanba and Shichuan Chuanba with RCC, it took advantage of the increased height of Xinzhongyueba from May to October 1980 to do a new practical study on the construction of the weak pier at the downstream of the dam According to the construction experience of the above three dams, Tamagawa dam also adopted RCC dam construction technology.
