1 前言在建筑工程中采用水泥土搅拌桩加固软土地基,提高地基承载力,技术上早已成熟,作为该技术应用领域的延伸,在河道治理岸边护坡工程中也获得了广泛的应用(长江、黄河岸边护坡),取得了较好的社会及经济效益。我们将水泥砂土搅拌桩应用于水利枢纽工程,在橡胶坝基形成抗冲防渗帷幕,成功地解决了南阳市第三级橡胶坝坝基抗冲防渗技术问题。
1 Preface The use of cement-soil mixing piles in the construction of soft soil to reinforce the foundation to improve the bearing capacity of the foundation, the technology has matured as an extension of the application of the technology in the river bank slope protection works have also been widely used (Yangtze River , The Yellow River bank slope protection), achieved good social and economic benefits. We apply the cement-sand mixing pile to the hydro-junction project to form the anti-seepage curtain on the rubber dam foundation and successfully solve the anti-seepage technical problems of the third-level rubber dam foundation in Nanyang.
