Abstract: The approach for the design and the beharvioural mechanisms of reinforced soil structures are presented in this paper.The Limit State Approach and aspects of partial factors for the design of geosynthetic reinforced soil structures are described emphatically.Application of the method for the design of a certain wall of flyash reinforced by geosynthetics, and the characteristic values and partial factors are discussed.This documentation is directly towards researchers and practionaires, and gives guidance for future research and development of codes for reinforced soil wall.

Key words: reinforced soil, geosynthetic, flyash, partial factors

摘要： 笔者介绍了加筋土的加固机理及设计方法,重点阐述了合成材料加筋土的极限状态设计方法的概念及分项修正系数,在一合成材料粉煤灰加筋土高支档的设计及验算中引入了分项修正系数,并对其主要设计指标确定进行了分析.本文对从事这一领域研究和工作的人员,以及今后规范的修订具有参考价值.
