| 摘 要： | 用边界元法从理论上分析非织造土工织物的拉伸性能。理论分析和试验表明：非织造土工织物的断裂强度随试样宽度的增加而增大。由于试样的不均匀性等原因，理论值一般高于试验值。通过回归分析得出非织遣土工织物试样宽度与断裂强度呈幂函数关系。

| Abstract: | The effect of nonwoven geotextiles specimen width on tensile properties is analyzed with the boundary element method. Theoretical analysis and experiment show that the breaking intensity of nonwoven geotextiles increases with increasing of the specimen width. The theoretical result is generally higher than the experimental result, due to unevenness of nonwoven geotextile and other reasons. Based on regression analysis, the power function would be used to describe the relationship between specimen width and breaking intensity of geotextiles. |
