    摘要
  • 摘要: 有纺土工织物反滤应用常处于双向受拉状态。孔径特征是有纺织物反滤设计的重要参数。由于双向拉应变引起孔径的变化显著,导致原本满足孔径指标的有纺织物时常反滤失效。根据有纺织物的微观结构及受力特点,分析双向拉应变导致条膜及孔径变化的机理,建立有纺织物单孔结构模型,推导孔径特征参数随双向拉应变变化的理论解,包括开孔面积率（POA,percent open area）及理论孔径（Obi）等。以等轴双向拉伸为例验证理论解。采用数字图像法在拉伸试验进行的同时,测试各级拉应变下3种单丝条膜有纺织物的孔径参数,包括开孔面积率、孔径分布曲线、等效孔径（O95）,分析各项孔径参数随拉双向应变的变化规律,并与理论解的预测结果进行对比。通过试验结果可见,理论解较好地预测了开孔面积率（POA）及等效孔径（O95）随双向拉应变的增大趋势,对变化斜率及数值的预测较准确,并得出孔径参数与等轴双向拉应变的近似线性关系,为反滤设计中预测孔径特征变化提供了理论依据。
    Abstract: The filtration applications of woven geotextiles are typically subjected to biaxial tensile strains. The pore size characteristics are important parameters in filtration design. Biaxial tensile strains can cause variations of pore size characteristics, which results in the failure of filtration. Depending on the microstructure of woven geotextiles, the variations of slit-films and pore sizes are analyzed. The mathematical model for strained microstructure of geotextiles is established. The analytical solutions of several pore size parameters corresponding to biaxial strains are proposed, including percent open area and analytical equivalent opening size. The equal biaxial tensile tests are carried out to verify the analytical solutions. The pore size parameters of three slit-film woven geotextiles subjected to different levels of strains are measured and analyzed through digital image analysis, including percent open area, pore size distributions and O95. The experimental results are compared with the analytical predictions. The analytical results correlate well with the experimental values and the rates of variations, and the pore size parameters change approximately linearly with the equal biaxial tensile strains.
