为了提高混凝土坝同土石坝竞争的能力,由美国工程基金委员会发起,1970年在美国加里福尼亚州的阿斯罗玛尔举行一次会议,讨论有关混凝土坝快速经济施工问题,参加会议的有美国土木工程学会,垦务局,陆军工程兵团等单位的代表80多位专家。会上第一项实质性的问题,就是“系统方法与混凝土坝设计及施工”。他们把系统方法作为一个工具,用来解决混凝土坝快速经济施工的某些问题,来提高混凝土坝的竞争能力。 In order to increase the ability of concrete dams to compete with earth-rock dams, the United States Engineering Fund Committee initiated a meeting in Asmaral, California, in the United States in 1970 to discuss the issue of rapid economic construction of concrete dams. More than 80 experts are represented by the American Civil Engineering Society, the Bureau of Reclamation, and the Army Corps of Engineers. The first substantive issue at the meeting was “Systematic Method and Concrete Dam Design and Construction.” They used the system approach as a tool to solve certain problems in the rapid and economic construction of concrete dams to increase the competitiveness of concrete dams.
