摘要
土工织物作为性能优越、价格低廉的新颖工程材料，具有特殊的水力特性、实验方法和设计准则，在水利工程及其他工程领域越来越多地被人们所重视和应用。本文在介绍土工织物滤层的作用机理和土工织物的水力特性的基础上，重点阐述了土工织物滤层设计方面有关孔径、渗透性、梯度等的计算方法和设计准则，提出了在设计中值得注意的问题和设计参数的确定，对土工织物滤层设计工作具有较好的指导和借鉴作用。
The geotextile is regarded as a new project material with property superior and price cheap. It has special hydraulic property, experimented method and design criterion. It is being attached importance and applied more and more in hydraulic engineering and other engineering realm.This paper is based on the hydraulic property and function of geotextile filtering layer,discussed computation method and dsign criterion of concerning hole diameter, permeability and grade etc. in the dseign of geotextile filtering layer, proposed some questions that must pay attention to and determination of design parameter in the design. It has better guidance and reference meaning for the design of geotextile filtering layer.
