GEOTEXTILES AND GEOMEMBRANES

Geotextiles are permeable fabrics which, when used in association with soil, have the ability to separate, filter, reinforce, protect or drain. As the use of geotextile fabrics has expanded there has been the introduction of geotextile composites and the development of products such as geogrids and meshes. Overall these materials are referred to as geotextiles and related products. All have a wide range of applications and are currently used to advantage in many civil engineering applications including roads, airfields, railroads, embankments, retaining structures, reservoirs, canals, dams, bank protection and coastal engineering. Geomembranes are impermeable membranes used widely as cut-offs and liners. Until recent years, geomembranes were used mostly as canal and pond liners; however, one of the largest current applications is to the containment of hazardous or municipal wastes and their leachates. In many of these applications geomembranes are employed with geotextile or mesh underliners which reinforce or protect the more flexible geomembrane whilst also acting as an escape route for gases and leachates generated in certain wastes. The range of products and their applications has expanded rapidly over the last decade with geotextiles and geomembranes being specified world wide. This rapid growth is paralleled by a virtual explosion of technology. Current reference books and even manufacturers' sponsored publications tend to date very quickly and the need for a vehicle to bring together and discuss the growing body of technology now available has become evident. Geotextiles and Geomembranes fills this need and provides a forum for the dissemination of information amongst research workers, designers, users and manufacturers. By providing a growing fund of information the journal increases general awareness, prompts further research and assists in the establishment of international codes and regulations. Types of Contribution Refereed technical papers covering research, design, construction, applications and case studies; technical notes, book reviews, reports of conferences and meetings, and letters to the Editor. All technical papers are open to written discussion. No limit to length is set and short notes are acceptable. Review articles may also be published at intervals, but the subject and contents of these should be discussed first with the Editor.

土工织物是渗透性织物，当与土壤结合使用时，具有分离、过滤、加固、保护或排水的能力。随着土工布用途的不断扩大，土工布复合材料的引入和土工格栅、网格等产品的开发也随之兴起。总的来说，这些材料被称为土工布和相关产品。它们都具有广泛的应用范围，目前已在许多土木工程应用中发挥优势，包括道路、机场、铁路、堤防、挡土墙、水库、运河、大坝、护岸和海岸工程。土工膜是一种不透水的膜，广泛应用于隔断和内衬。近年来，土工膜主要用作运河和池塘的衬砌;然而，目前最大的应用之一是控制危险或城市废物及其渗滤液。在许多这些应用中，土工膜与土工织物或网眼衬底一起使用，这些衬底加强或保护更灵活的土工膜，同时也作为某些废物中产生的气体和渗滤液的逸出路线。随着土工织物和土工膜在全球范围内的应用，土工织物及其应用的范围在过去十年中迅速扩大。与这种快速增长相对应的是技术的虚拟爆炸。目前的参考书，甚至是制造商赞助的出版物的日期往往非常快，显然需要一种工具来汇集和讨论日益增长的现有技术。土工织物和土工膜满足了这一需要，并为研究人员、设计师、用户和制造商之间传播信息提供了一个论坛。通过提供越来越多的资料，该杂志提高了一般的认识，促进了进一步的研究，并协助建立国际守则和条例。参与研究、设计、建造、应用及个案研究的科技论文;技术说明、书评、会议报告和给编辑的信。所有技术论文都可以书面讨论。没有长度限制，短笔记是可以接受的。评论文章也可以间歇发表，但主题和内容应首先与编辑讨论。
