土工织物拉伸试验测试仪器及方法

摘要

抗拉强度及延伸率是评价土工织物拉伸性能的主指标，抗拉强度试验测试结果的有效性直接影响到对工程实践的指导。通过对国内外各种有关土工织物拉伸试验研究成果的总结，对各种测试方法给予了客观的分析，并在此基础上提出了土工织物多向拉伸的设想。结合工程实际，从理论可行的角度设计了两种多向拉伸试验仪器，对土工织物拉伸试验测试方法的改进提供了参考依据。%Abstract: The tensile strength and elongation are key performance indicators of geotextile,and the effectiveness of the tensile strength test method has a direct impact on engineering practice guidance. Various of relevant geotextile tensile test results from domestic and foreign have been summarized, while an objective analysis was given to those methods, and on basis of this came to the idea of multi - directional tensile test. Based on engineering practice, two multi - directional tensile test instruments are designed from the point of theory. All those will provide a reference to the improvement of test methods for geotextile tensile test.
