【摘要】 为了研究交通荷载作用下影响软基加筋道路加筋效果的因素,采用有限元方法分析了荷载大小、面层刚度、筋材模量、面层厚度、基层厚度、基层刚度等对加筋效果的影响.结果表明,随着交通荷载的增大,加筋的效果越来越明显.随着面层刚度的增大,加筋效果逐渐减小.随着面层厚度的增大,加筋的效果越来越小.加筋效果会随筋材模量的增大而增大,但达到一定值以后,这种增大的趋势逐渐变得不明显.随着基层厚度的增大,加筋的效果减小很快.更多还原

【Abstract】 A series of finite element simulation were carried to investigate the beneficial effects of geogrid re- inforcement to the vertical displacement,and how such effects were influenced by the load magnitude,pavement stiffness,pavement thickness,geogrid module,base stiffness and base thickness.FEA results indicated that the greater the load magnitude was,the bigger the beneficial effects of geogrid reinforcement was.With the increase of geogrid modulus,the effect of reinforcement increased.With the increase of pavement stiffness and pavement thickness,the effect of reinforcement decreased.The effect of reinforcement decreased with the increase of base stiffness and base thickness.更多还原
