在国内外的坝工建设中,土石坝作为一种传统的坝型得到了广泛的应用,其具有材料来源广、结构简单、技术成熟等优势。在土石坝设计中,国内外已经积累了较为丰富的工艺和技术经验,但是在接合部位的处理方面仍然存在一定的弊端,如果不能采取科学、有效的处理方法,将严重危及到土石坝的整体牢固性、安全性和抗震性,所以,必须引起工程设计人员的高度重视。 In the dam construction at home and abroad, the earth-rock dam has been widely used as a traditional dam type. It has the advantages of wide source of raw materials, simple structure and mature technology. In the design of earth-rock dam, the domestic and foreign countries have accumulated rich experience in technology and technology, but there are still some drawbacks in the treatment of the joint. If we can not take a scientific and effective approach, it will seriously endanger the overall dam Solidity, safety and shock resistance, therefore, must attract the attention of the designers.
