Geomembrane State-of-Practice Paper and Vision Paper Development

*9908067 Elton土工合成材料是用于改善土工性能的聚合物板材，是具有成本效益的土木工程的重要组成部分。土工合成材料包括土工布、土工膜和许多防侵蚀材料。所有这些都被灵活地用于垃圾填埋场，以保护环境。土工合成材料的开发和使用一直非常迅速；事实上，如此之快，以至于设计和安装土工合成材料的知识和经验的转移跟不上市场的快速扩张。其结果是不必要的失败。如果在一份共同的文件中分享和公布其他人的经验，许多失败是可以避免的。尤其是在垃圾填埋场中使用土工合成材料，特别是土工膜。使用垃圾填埋场土工膜的无党派专家将出席并分享在开放环境中的经验。研讨会的题目是土工膜测试和修复技术-土工膜材料、接缝和安装的衬里系统的测试，以及后者中泄漏的修复。研讨会的目标是：1.制定一份实践状况报告2.就这一主题在哪里需要新的知识/研究以及如何获得新的知识/研究提出专业的愿景3.为其他组织(如ASCEGeo-Institute)举办类似的研讨会/集思广益会议提供模式。在实践状况文件((1))完成后，10名专家专业人员将参加在亚利桑那州奥本大学举行的为期2.5天的研讨会，分享经验并讨论该专业在这一领域的需求。会议结果将是关于该专业在未来五年的需求的论文。*

***9908067EltonGeosynthetics, polymeric sheets used to improve earth behavior, are animportant part of cost-effective civil engineering. Geosynthetics includegeotextiles, geomembranes and many erosion control materials. All are usedextensively in landfills to protect the environment. The development and use ofgeosynthetics has been very rapid; so rapid, in fact, that the transfer ofknowledge and experiences from designing and installing geosynthetics has notkept up with the rapid expansion of the market. The result is needlessfailures. If the experience of others had been shared and publicized, in acommon document, many failures could have been avoided. This is especially truein the use of geosynthetics, particularly geomembranes, in landfills.A workshop with resulting documents is proposed. Non-partisanexperts inthe use of landfill geomembranes will attend and share experiences in an openenvironment. They will discuss current problems and focus on better solutions.The workshop title is Geomembrane testing and remediation technologies -testingof geomembrane materials, seams, and installed lining systems, and the repairof leaks in the latter. The workshop goals are:1. develop a state-of-practice paper 2. provide a vision for the profession on where new knowledge/research is needed on this subject and how to get it3. provide a model for other organizations (such as the ASCEGeo-Institute)to hold similar workshops/brainstorming sessions. After the state-of-practice paper ((1) above) is complete, ten expertprofessionals will attend a 2.5-day workshop at Auburn University in Auburn,AL, to share experiences and discuss the needs of the profession in this area.The meeting results will be a paper on the needs of the profession on thesubject for the coming five years.***
