土工合成材料在防汛抢险中的应用

土工合成材料具有整体性强、抢险速度快、适应性强、储运方便、造价低、经久耐用和可废物利用的优点，在防汛抢险中主要起到排水、反滤和防渗的作用，常用于堤岸崩塌、基础管涌、堤身跌窝与漏洞、背水坡散浸、背水面脱坡、洪水浸顶和防风浪淘刷、涵闸及堵口等方面，可及时排队险情。

Exercise of Geo-technical Composite Materials in Flood Defense

Geo -technical composite materials are characterized as strong in comprehensive uses and release danger in fast speed, and super in suitability, easy to transport, low cost, long lasting and recycling. It has functions of drainage, anti-filtering and seepage prevention, which is often used for protecting dyke collapse, failure by piping at foundations, drop pit of bank body and leakage holes, scattered seepage of land-side slope, sloughing of land-side slope, overtopping of flood, undercutting of wind-wave, and also used for culverts and plugging for getting rid of danger timely.
