摘要

地工織物為柔性之工程材料，於70年代末問世以來，即以線性快速成長，至今已成大地工程解決疑難雜症之利器；但地工織物牽涉到高分子材料、紡織及大地工程，雖為大地工程所應用，但其性質及行為取決於高分子材料與紡織製程，故如何恰當、允當使用地工織物為一重要課題。本文以AASHTO M 288－96規範為例，闡述地工織物之應用；於特定之應用，地工織物所扮演之功能，及涵蓋紡織及大地工程所應考量之物理、化學及力學因素，需求之地工織物性質，供大地工程師在地工織物應用之省思及參考。

Geotextiles are soft engineering materials. From the end of 1970, geotextile's application in geotechnical engineering has grown rapidly and become a great tool for solving geotechnical problems. Geotextile includes polymer, textile and geotechnical engineerings, although used by geotechnical engineer, its properties and behaviors are related to polymer materials and textile manufacturing process. It is an important topic on how to use geotextile properly. In this paper, using AASHTO M 288-96 Specifications explains the applications of geotextile. In the specialized applications, the functions of the geotextile and the factors of the physical, chemical and mechanical properties of geotextiles covered in textile and geotechnical engineering as well as required properties for the application are introduced.
