1956年以来,苏联的水电建设开始转向高水头工程的开发。在尔后的20多年中,先后在不同气候条件下和地震区兴建了不少超过100甚至200m的高坝。表1所列为其中一些混凝土重力坝。这些坝都是根据1960年规范进行设计的。但通过这些坝的设计、模型试验及原型观测,于1977年制订并颁发了新的重力坝 Since 1956, the construction of hydropower in the Soviet Union has shifted to the development of high-head projects. In the following 20 years, many high dam of more than 100 or even 200m have been built successively in different climatic conditions and in the earthquake area. Table 1 lists some of these concrete gravity dams. These dams were designed according to the 1960 regulations. However, through the design, model testing and prototype observation of these dams, a new gravity dam was formulated and issued in 1977
