Abstract: This paper reflected the types and the characters of geosynthetics, and the technique of reinforced soils applied to certain fields in Geotechnical Engineering was presented systematically, in particular to the MSEW and the RSS .The soft soil, the subgrade soils and the in-situ slops enhanced with Geosynthetics as well as FRS were biefly summarized .Furthermore , the methodology of design for reinforced soils the research on theworking mechanism models were discussed emphatically , and besides, the recent development of the technique of reinforced soils applied to this domain was expounded

Key words: geosynthetics , mechanically stabilized earth wall, reinforced soils slopes

摘要： 介绍了土工合成材料的种类与功能，特别是合成材料在岩土工程加筋土技术中的各类应用，主要是加筋土 挡墙和加筋土坡，还包括了软土地基加固、路基基层加筋、原位边坡加固以及纤维加筋土。并进一步阐述了加筋 土技术应用的最新发展，重点分析了加筋土结构的设计原理和工作机理。
