我国应用化学灌浆处理岩石坝基,已有二十多年历史。特别是在最近十年内,发展很快。现在它已经成为基础处理工程中的新技术而受到重视,并已在一些地质条件比较复杂的工程中,成功地解决了一些水泥灌浆所不能解决的工程难题。在灌浆材料选择、灌浆理沦和控制技术、灌浆工程设计以及灌浆帷幕结构没计等方面都积累了许多经验,取得了不少研究成果。本文结合这些经验和成果,对以上各个问题进行了初步探讨,并得出了相应的结论。
China’s application of chemical grouting rock dam foundation, has more than 20 years of history. Especially in the last ten years, it has developed rapidly. Now that it has become the foundation of new technologies in engineering, attention has been given to it and some of the engineering problems that can not be solved by cement grouting have been successfully solved in some complicated geological conditions. Many experiences have been accumulated in the selection of grouting material, grouting theory and control technology, grouting engineering design and grouting curtain structure, and many achievements have been made. Based on these experiences and achievements, this article has carried on the preliminary discussion to each question above, and has drawn the corresponding conclusion.
