| 摘 要： | 为了评价目前中国有关土工织物测试规范中规定的试验方法的适用性,对无纺土工织物的透水与反滤性能进行了试验研究。研究采用正交试验等方法对无纺土工织物的物理和水力学性能参数进行了测试,通过统计分析,得出了其水力学参数之间的相关关系,分析了土类、织物厚度、水力梯度和渗透系数等因素对其反滤性能的影响,初步推荐了对公路土工织物进行分类的指标及数值和其满足滤层要求的设计标准。 |

| Abstract: | In order to evaluate the applicability of the test methods of geotextile which are prescribed in domestic test standards,authors conduct test researches on penetrative and filtration properties of nonwoven geotextile.By adopting orthogonal test method etc,authors test the parameters of physical and hydraulic properties of nonwoven geotextile.Through statistical analysis,authors arrive at interrelated relationships of the hydraulic parameters, analyze the influences of some factors on filtration properties, which include kinds of soil,thickness of fabric, hydraulic gradient and coefficient of permeability.Finally,authors preliminarily recommend the classified index and the numerical value of road geotextile,and also the design standard which meets with the requirement of the filtration lay. |
| Keywords: | road engineering nonwoven geotextile orthogonal test penetrative and filtration property vertical coefficient of permeability gradient ratio |
