现代坝工技术及其发展趋势(一)

History of Modern Dam Technique and Development Tendency

简要回顾坝工技术发展的历史，重点介绍重力坝、拱坝和土石坝等坝型在设计理论、设计方法和筑坝技术等方面的发展过程和当前研究水平，针对计算分析中存在的问题，反分析研究愈来愈受到重视．同时也对当前流行的碾压混凝土坝、混凝土面板堆石坝、复合土工膜防渗土石坝等新材料、新坝型、新技术进行了论述．在深厚透水坝基防渗处理方面重点介绍混凝土防渗墙技术和高压喷射灌浆处理技术等．

History of dam technique development is reviewed briefly.The development process and level of gravity dams,arch dams and earth rockfill dams are introduced in design theory,design method and dam construction technique.To counter existential problems,people pay attention to inverse analysis research more and more in calculating analysis.At the same time new materials,new dam types and new techniques of current rolled concrete dams,concrete face rockfill dams and earth rock dams with geomembranes is disscussed.The technique of concrete cut off walls and high pressure jet grouting are introduced mainly in seepage prevention of deep seepage dam foundation.
