近年来,地处黄河三角洲地区的胜利油田在水利工程施工中使用了大量的土工布。特别是在水库围坝护坡工程上,通过不断的研究、试验,摸索出了一套适合黄河三角洲地区土体特性的护坡土工布反滤方案,已经在4个水库上推广应用,取得了良好的社会经济效益。土工布作为一种新型滤料用于坝体反滤结构时,关键在其透水、保砂(即防止被保护土体的冲刷)作用。黄河三角洲为黄河携带泥沙于河口入海处流速减缓逐年沉积而成,地层为第四纪最新沉积层,土料大部分为
In recent years, Shengli Oilfield, located in the Yellow River Delta region, has used a large amount of geotextiles for water conservancy projects. Especially in the dam slope protection project, through continuous research, test, worked out a set of suitable for the Yellow River Delta soil properties of the slope protection geotextile filtration program, has been in the four reservoir on the promotion and application, made a good Social and Economic Benefits. Geotextiles as a new type of filter used in the dam body filter structure, the key in its permeability, sanding (that is, to prevent the protection of soil erosion) role. The Yellow River Delta sediments from the Yellow River to carry sediment slowed down into the sea sediment deposition from year to year, the latest sedimentary layer of the Quaternary, most of the soil material
