摘要

地工合成材料為土木營建新興施工材料，其大致包括地工織物、地工格網、地工止水膜、地工排水網、地工粘土毯、地工排水管、地工複合材、及地工泡沫材等八大類，其應用功能包括區隔、加勁、濾水、排水、防漏、保護、及防沖蝕。設計上地工合成材之選用除需滿足其應用功能外，亦需考慮其性能是否可滿足規範之要求，及其於市場上之供應情形及價格等因素。目前地工合成材於工程之應用上已日益普遍，因此本文乃針對地工織物、地工止水膜、及地工格網目前CNS、ASTM、及GRI所包含之相關規範，簡要地敘述，供工程界先進參考。

Geosynthetics exclusively are human made new construction materials which have influenced the construction in the areas of geotechnical engineering, transportation engineering, environmental engineering, and hydraulics engineering, etc. The families of Geosynthetics include Geotextiles, Geogrids, Geomembranes, Geonets, Geosynthetic clay liners, Geopipes, Geocomposites, and Geofoams. Geosynthetic materials perform seven major functions: separation, reinforcement, filtration, drainage, liquid barrier, protection, and erosion control. For a particular application design, the ultimate decision usually take one of the three directions: design by cost and availability, design by function, and design by specification. Since the new materials are widely used in various construction, design by specification is very common and exclusively important when dealing with public agencies. The objective of the paper is to review the current common used CNS, ASTM, and GRI test standards for Geotextiles, Geomembranes, and Geogrids.
