土工布的拉伸特性及各向异性研究

Study of the Stretching Properties and Anisotropy in Geatextile

本文对三种类型土工布进行拉伸特性实验研究,获得了单向拉伸和双向拉伸性能的重要参数,对其结果进行了理论分析;对土工布各向异性弹性模量也进行实测及理论计算,获得较理想的近似性,此项实验研究结论为工程设计提供了可靠的依据。

The Stretching properties of three kinds of geatextiles by experimental method have benn studied in this paper.The important parameters of unlateral and biaxial stretching are obtained and the results are analyzed.It has made the measure and calculation of anisotropic modulus of elasticity,which has idealer approximate value.This experimental study results provide the reliable basis for engineering design.
