辽宁省水利工程应用土工合成材料的效益分析

Analysis of Benefits of Geosynthetics used in Liaoning Provincial Water Conservancy Projects

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 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.
