1 应用现状防汛抢险所用材料要求重量轻、便于运输、不易腐烂,施工简单、快捷、见效快,而土工合成材料所具有的特点正好能满足防汛抢险的要求。土工合成材料应用于岩土工程是近50年来发展起来的一门新技术,70年代末引入我国。1985年云南省陆良南盘江左岸堤坡脚汛期的巨大管涌破坏,曾用无纺土工织物作滤层,上覆毛石压重排除了险情。继后在长江中下游和北方大江大河的防洪堤上先后用土工合成材料排险和兴建护坡护堤工程。1991年开始,国家防汛抗旱总指挥部将土工合成材料作为防汛抢险物料下达生产储备任务,各流域都分别储存了编织袋、复合布、土工织物、防
1 Application Status Flood prevention and rescue materials used in the request of light weight, easy to transport, non-perishable, construction is simple, fast, quick, and geosynthetics have the characteristics just to meet the requirements of flood control. Geosynthetics used in geotechnical engineering is a new technology developed in the past 50 years, introduced into China in the late 1970s. In 1985, Luliangnan, Yunnan Province, left bank of the bank of the bank slope foot flood damage during the flood, once with non-woven geotextile filter layer, overweight rubble excluded the danger. Successively in the Yangtze River and the northern river flood levee has geotextile materials and the construction of slope protection berm project. Since 1991, the State Flood Control and Drought Relief Headquarters has taken geosynthetics as a task of production and storage for flood control and emergency rescue materials. Each basin has stored woven bags, composite cloths, geotextiles,
