【摘要】 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．更多还原

【Abstract】 The benefits of geosynthetics used in Liaoning provincial conservancy projects are analysed.The results of the analysis reveal that the geotexture flexible raft for protecting banks can save investment by 35%～38% compared with the traditional raft,and geotexture filter for protecting slopes of dams can save investment by more than 30% compared with the sand gravel material filter,and the geomembrane for preventing seepage can save investment by 30%～50% compared with cohensive soil.At the same time,geosynthetics can generate remarkable social benefits in ecological balance,energy and chemical fibre industries,etc.更多还原
