CAREER: Nondestructive Evaluation of Geomembranes

PI: Nazli Yesiller: Wayne州立大学“土工膜的无损评估”，本研究的目的是发展无损检测技术来表征土工膜，并确定实验室和现场的物理，机械和降解性能。将建立无损检测参数、材料性能和土工膜微观结构之间的基本相关性。NDT方法为传统测试方法提供了快速、简单、灵敏的测试替代方案，并且可以在现场进行测试，而不会干扰原位土工膜。本研究建议使用的无损检测方法包括液体渗透检测和超声波检测。在这项工作的研究部分获得的经验将用于在现有的以设计为导向的土工合成材料课程中增加一个实验室课程。在研究中发展的测试方法将用于在堆填区设计和土木工程材料课程的演示。＊＊＊

Abstract Proposal: CMS97-01947 PI: Nazli Yesiller: Wayne State University "Nondestructive Evaluation of Geomembranes" The objective of this study is to develop nondestructive testing techniques to characterize geomembranes and to determine the physical, mechanical, and degradation properties both in the laboratory and field. Basic correlations will be established between NDT parameters, material properties, and microstructure of geomembranes. NDT methods provide fast, simple, and sensitive testing alternatives to conventional testing methods, and the tests can be performed in the field without disturbing in-place geomembranes. The NDT methods proposed for use in this study include liquid penetrant inspection and ultrasonic testing. The experience gained in the research component of this work will be used to add a laboratory session to an existing design-oriented geosynthetics course. The testing methods developed in the study will be used for demonstrations in Landfill Design and Civil Engineering Materials courses. ***
