Abstract: The current specification for reinforced etuth retaining wall is mainly adapted to the plastic or steel-plastic belt. ctually, the widespread application for geoElTid in current engineering construction lacks for correlated theory and method. Fonn the interaction mechanism with geognd and soil, the text mainly introduces the design about reinforced retaining wall with geogrid.Using the soil theory of Rankine.Coulomb and Boussinesq etc. and consulting the foreign experience about engineering application for geosynthetics, the paper presents the design methods and formulas for the internal and external stability about the geogrid reinforced earth retaining wall ard gives an application example .

Key words: geogrid reinforced earth, retaining wall, design method

摘要： 现行加筋挡土墙规范主要是针对条带式加筋挡墙的情况而制定，而近年来实际工程中大量采用土工格栅修 筑加筋挡墙的工程应用却缺乏相关设计规范和设计方法的支持．本文主要从土工格栅对土体的加固机理出发介绍 土工格栅设计加筋土挡墙的相关设计理论和方法，借助Rankine、Coulomb、Bo~q(布西奈斯克)的土体理论，同时 参考国外的土工合成材料设计理论比较系统地介绍了土工格栅加筋挡墙的内部和外部稳定性验算方法，并给出具 体的应用算例
