USD(上静水坝)位于犹他(Utah)州的尤恩他(Uinta)山区,海拔2438m,是目前世界上最大的碾压混凝土坝.该坝完成于1987年8月,直线型重力坝坝高88m,坝体混凝土总量为122万m~3,其中绝大部分(112万m~3)为RCC(碾压混凝土),有69000m~3的混凝土为用滑模施工的护面层.由坝蓄存的水将经由放水隧洞输送到城市的居民区和工、农业生产区,该工程是犹他州重点规划项目的一部分.坝址区的高程及其地理位置对于混凝土的施工来说,环境气温是偏低的,年平均温度为2.2℃,因此混凝土的浇筑必须安排在一
USD (Upper Static Dam) Located in the Uinta mountains of Utah, at an altitude of 2438m, it is the largest RCC dam in the world and was completed in August 1987. The height of the linear gravity dam 88m, the total amount of dam concrete is 1.22 million m ~ 3, most of which (1.12 million m ~ 3) is RCC (RCC), and 69000 m ~ 3 concrete is the surfacing layer constructed by sliding mode. The dam’s stored water will be delivered to urban neighborhoods and industrial and agricultural production areas via drainage tunnels, which are part of Utah’s key planning projects. Upgrading and Geographical Location of Dam Sites For concrete construction, the environment The temperature is low, with an average annual temperature of 2.2 ℃, so pouring of concrete must be arranged in a
