高水坝溢洪道混凝土，在水通道速度高达30-50米/时能提供足够的抗汽蚀性能和所需的抗冻性能。300-500公斤/米3的普通硅酸盐水泥通常用于准备这样的混凝土。在规范的地区中，空蚀和耐磨损的混凝土需要不超过0.5-1M [1]。然而，现有的标准限制以外的任何区域的最小宽度为2米[2]。在柱状大坝中切片外区的大小等于列的长度（11-27米）。因此，混凝土的大小在大坝设计中指定的溢洪道表面规格成倍的超过必要的尺寸。例如，当reequipping到服务网点的Sayano-Shushenskoe的大坝导流oudets hydrostation安置M400型的W12的F400级混凝土用波特兰水泥450-500公斤/立方米，厚度4-15，在基础上冷却面积7×80米的混凝土，指定为每10个网点一米。

CRACK RESISTANCE OF CONCRETE MEMBERS OF OUTLET WORKS

Concretes of spillways of high dams should provide cavitation resistance during passage of water with velocities up to 30-50 m/see and the required frost resistance. Portland cement (PC) with contents of 300-500 kg/m 3 is usually used for preparing such concretes. From the specifications the zone of cavitation- and wear-resistant concretes need not exceed 0.5-1m [1]. However, the existing standards limit the minimum width of any outside zone to 2 m [2]. In dams with columnar sectioning the sizes of the outside zones are taken equal to the length of the column (11-27 m). As a result, the sizes of the zones of concretes meeting the specifications for spillway surfaces designated in dam designs exceed the necessary sizes manyfold. For example, when reequipping the diversion oudets into service outlets on the dam of the Sayano-Shushenskoe
