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-筋材的相互作用.以岩土工程专业有限元程序Phase2V6.0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.
Stability analysis of embankment reinforced with geosynthetics 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）, Phase2 V6.0, a commercial software written for geotechnical engineering was performed to analyze the slide behavior of embankment reinforced with geosynthetics.
