| 摘 要： | 收集了国内外有关土工织物渗透性能的测试标准,并进行了比较。分析了土工织物的微观结构以及渗透原理,通过系列的试验数据探讨了土工织物渗透性能的规律,即水头差与流速的关系,比较三种拟合方式的拟合程度,提出最合适的拟合关系作为水头差和流速的理论关系式。分析比较几种检测标准取值的依据,提出检测结果取值的方案,为国家测试标准GB/T 15789-1995《土工布透水性测定方法》的修订提供依据。

| Abstract: | The related test standards of permeability for geotextiles home and abroad were collected and compared and the microstructure and permeation principle of geotextiles were analyzed in the paper.The law of permeability for geotextiles,that is relationship of head fall and current velocity was discussed by a series of test data.Three kinds of simulating test were presented in it and the optimum mimicry as theoretical formula on head fall and velocity of flow was offered.The scheme of drawing figures from test results was pointed out by analyzing on basis of drawing figures,for providing the basis on revising for national test standard GB/T 15789-1995 . |
