对辽宁省水利工程应用土工合成材料进行效益分析，分析结果表明，采用土工织物软体排护岸比传统柴排护岸节省投资３５ ％ ～８０ ％ ；堤坝护坡采用土工织物滤层比传统砂砾料滤层节省投资３０ ％ 以上；土工膜防渗可比粘土防渗节省投资３０ ％ ～５０ ％ ．同时土工合成材料具有保护生态平衡、节省能源、促进化纤工业发展等十分显著的社会效益．
The results of the analysis show that the geotextile fabric can save 35% -80% of the investment in protecting the shores of the traditional firewood embankment, and the geotextile filter layer of the dam slope protection can save more than the traditional sand and gravel filter layer Investment more than 30%; geomembrane impermeable clay seepage control savings of 30% to 50%. At the same time, geosynthetics have significant social benefits of protecting ecological balance, saving energy and promoting the development of chemical fiber industry.
