日本修建高土石坝的历史不久,可是筑坝技术的发展是很快的。这是由于近年水资源紧张,在70年代后期,筑坝数量急剧增加,而条件良好的坝址缺乏,人口稠密,国民经济高度发达,社会上要求筑坝要谨慎,要绝对安全可靠,然而少量事故还是发生的,这就是使近年来筑坝技术发展很快的主要原因。他们提高筑坝技术的具体做法,是在调查,设计,施工以及管理等四个步骤中采用了新技术与新理论,例如坝工结构改进,新施工方法,新性能的大型施工机具及电子仪器包括电子计算器等新技 Japan’s history of building high earth and rock dam soon, but the development of dam technology is fast. This is due to the tense water resources in recent years. In the late 1970s, the number of dams has risen sharply. However, due to the lack of well-developed dam sites, densely populated areas, highly developed national economy and cautious damming in the community, it is absolutely safe and reliable. However, a small amount Accident still happens, this is the main reason for the rapid development of dam technology in recent years. Their concrete approach to improving dam construction technology is to adopt new technologies and theories in four steps: investigation, design, construction and management, such as improvement of dam structures, new construction methods, large-scale construction machinery and electronic equipment with new properties Including electronic calculators and other new technologies
