水库的安全是一个经久不息的话题,水库安全关系到社会的稳定和人民群众的生命财产安全,国内外众多专家学者一直致力于这方面的研究。当前在大坝安全防渗方面采用的技术措施就是防渗墙,随着对渗流理论研究的深入,防渗墙技术日趋成熟,已经应用到越来越多的水库大坝工程中。文章从防渗墙的材料、施工以及防渗理论着手,简单介绍了防渗墙在水库大坝工程中的应用。
The safety of reservoirs is an everlasting topic. The safety of reservoirs is related to social stability and people’s lives and property safety. Many experts and scholars both at home and abroad have devoted themselves to this research. At present, the technical measure adopted in dam seepage prevention is the cut-off wall. With the further study of seepage theory, the technology of cut-off wall has matured and has been applied to more and more reservoir dams. The article starts with the material, construction and seepage prevention theory of impervious wall, and simply introduces the application of impervious wall in reservoir dam engineering.
