平原水库的坝坡护砌是平原水库修建的重点问题,其工程量大,投资比例大,机械化程度低,对土坝的防护功能要求较高,尤其在石料缺乏地区,更成为制约平原水库建设投资、质量、工期的关键问题。丁东水库在建设中大规模地采用了土工织物作为护坡反滤层,取得了良好的效果。现对土工织物在丁东水库坝坡护砌中的应用阐述如下: The dam slope protection of plain reservoirs is a key issue for the construction of plain reservoirs. Due to its large amount of engineering, large investment, low mechanization and high requirements on the protection of earth dam, especially in areas with a shortage of stone, it has also become a constraint to the construction of plain reservoirs Investment, quality, duration of the key issues. Dingdong Reservoir in the construction of large-scale use of geotextile as a slope protection filter, and achieved good results. The application of geotextile in the dam slope protection of Dingdong Reservoir is described as follows:
