影响加筋垫层作用效果的主要因素

The Main Factors that Influence the Properties of Reinforcement Layer

本文结合室内模型试验,利用有限元法,研究了影响加筋垫层作用效果的主要因素。分析结果表明,影响加筋垫层作用效果的主要因素是筋材种类和布置、筋材刚度、地基土强度。在一定范围内,加筋垫层的作用效果随着筋材刚度的增大而增大,随着地基土强度的增大而减小,而地基刚度对加筋垫层作用效果的影响不显著。

This paper studies on the main factors that influence the effect of reinforcement layer by model test and finite element a nalysis. The analysis reveals that the main factors include the reinforcement＇s style, layout and rigidity, the strength of ground soil. The effect increases by the increase of the reinforcement＇s rigidity, but decreases by the increase of the ground soil＇s strength. The influence of ground soil rigidity is not notable.
