摘　　要：介绍了土工合成材料在辽宁省大洼三角洲应用于防洪护岸工程的情况。通过室内试验,对这种土工合成材料的物理力学特性、渗透性及反滤特性进行了试验研究。试验结果表明,非标准渗透仪可以代替标准渗透仪对防护工程进行试验研究。由于非标准仪尺寸大,更接近工程实际情况,所以可以更好地模拟工程条件,更具有对防护工程进行实验研究的实际意义。The geo-textile fabric utilization in Dawa delta, Liaoning Province in the flood prevention-shore protecting project was introduced. By indoor test, the mechanical characteristic, the permeability and the counterpermeability were studied. The testing result reveals that the standard permeation apparatus can be substituted by non-standard permeation apparatus to conduct the experimental research. Because the non-standard permeation apparatus is larger in size and is more similar with the real engineering practice, it is better to simulate the engineering condition and is more useful to investigate the defensive project with experimental measures.
