摘　　要：土石坝防渗土工膜材料多种多样,土工膜受生产工艺的限制在进行大面积布设时必须进行拼接,因此很有必要针对不同的拼接方法进行详细分析。结合规范中土工膜的拼接效果评价标准,论述了土工膜拼接质量现场检测各种方法的原理和技术要求,在此基础上对国内外有关土工膜拼接方法的研究成果进行了总结。按照土工膜拼接过程中是否有化学反应发生,将拼接方法分为物理方法和化学方法,并详细论述了各种方法的工作原理、适用范围及优缺点。最后,结合研究的现状提出一些与土工膜拼接有关的问题。There are various kinds of waterproof geomembrane materials for earth rock dams. Due to the limitations of production process, the geomembranes have to be spliced when layed in a large area. Firstly, the principles and technical requirements for the on-site inspection of splicing quality are discussed with reference to the specifica- tions. Research achievements of splicing geomembrane in China and abroad are summarized. What＇ s more, the splicing techniques are divided into physical methods and chemical methods. The working principle, application scope, advantages and defects of each method are presented in detail. Finally, problems in the current research are put forward.
