摘要
根据对国内若干座大坝的防渗帷幕运行情况进行的工程实例调查和资料分析,讨论国内外热议的大坝帷幕防渗能力衰减问题。认为我国水库大坝防渗帷幕大部分运行正常或基本正常,不存在帷幕防渗能力普遍衰减的情况;少数帷幕防渗能力衰减的主要原因并非灌浆浆液太稀所致;影响防渗帷幕耐久性的主要因素有设计质量、施工质量、不良地质条件和浆材浆液等;欧洲一些水利工程发生帷幕防渗能力衰减现象较为普遍,有可能是灌浆方法简单和防渗标准较低所致。
According to case studies and data analyses of operation of anti-seepage curtains for some dams in China,the worldwide hot topic on the attenuation of anti-seepage capacity of curtain for reservoir dams was discussed.A conclusion is drawn that the operation of most anti-seepage curtains for reservoir dams in China is normal or basically normal,and the attenuation of anti-seepage capacity of curtains is not common.The attenuation of anti-seepage capacity of some curtains is not induced by thin grouting.The main factors for the durability of anti-seepage curtains include design quality,construction quality,poor geological conditions and grouting materials,etc.The attenuation of anti-seepage capacity of curtains for some hydraulic projects in Europe is prevalent.It may be aroused by simple grouting method and low anti-seepage standards.
