坝体防渗设计中膨润土防水毯的应用

Application of Geosynthetic Clay Liner to anti-seepage system in dam body

为了简化施工方法、克服施工环境限制条件、环保等方面的不利因素,娲皇宫生态水域工程拟采用膨润土防水毯(GCL)作为坝体防渗材料,结果表明,该技术所得各项指标和效益大大优于传统的防渗技术。因此,这种绿色环保型的防水防渗材料与简便易行的施工方法完美结合而成的GCL技术具有极大的可行性。

The Geosynthetic Clay Liner is planned to be applied to the construction of Wa Imperial Palace Ecological Reservoir Project, so as to simplify the construction method and overcome both the limits of construction environment and the unfavorable factors in the aspect of environment protectiorL The study shows that all the indexes and the benefits from this technique are much better than those from the traditional anti-seepage technique. Consequently, the technique of GCL（ Geosynthetic Clay Liner） perfectly combined with this kind of green environmental anti-seepage material and the simphfied construction method has a great fea- sibility to be adopted in the construction of the project concerned.
