自70年代以来,土工合成材料的研究和应用得到迅猛发展。由于其造价较低、施工简易、储运方便、耐腐蚀等优点和排水反滤、隔水防渗、柔性护底、可加肋压载等诸多特点,我国已成功地将土工合成材料运用于海岸防护工程,并获得了明显的经济和社会效益。本文在分析我国土工合成材料应用需求和各类产品特性的基础上,重点介绍该材料在海岸防护工程中的应用(试验)实例。 Since the 1970s, the research and application of geosynthetics have been rapidly developed. Due to its low cost, easy construction, storage and transportation, corrosion resistance and other advantages of drainage and filtration, impermeable seepage, flexible protective bottom, can be added rib ballast and many other features, China has successfully applied to geosynthetics Coast protection project, and access to significant economic and social benefits. Based on the analysis of the application requirements of geosynthetics in our country and the characteristics of various products, this paper mainly introduces the application (experiment) of this material in the coast protection engineering.
