Abstract

Abstract: Stability analysis of embankment reinforced with geosyntheties has been a great concern for highway engineers．To overcome some disadvantages of traditional limit equilibrium method(LEM)，based on the shear strength reduction method (SSRM)，Phase7．V6．0，a commercial software written for geotechnieal engineering Was performed to analyze the slide be- havior of embankment reinforced with geosyntheties．

Key words: highway enginering, embankment reinforced with geosyntheties, shear strength reduction method, stability analysis

摘要： 稳定性是加筋土路基设计首先应考虑的问题．以往的加筋土路基稳定性分析多采用传统的极限平衡法 (LEM)，并简单地将筋材的作用等效为拉力，而忽略了土体一筋材的相互作用．以岩土工程专业有限元程序Phase2 V6．0为研究平台，建立真实反映加筋土路基力学行为的精细数值分析模型，运用剪切强度折减法(SSRM)，分析加筋土路基的稳定性．
