摘要
采用非线性有限元方法,通过比较土工格栅加筋路堤和未加筋路堤来分析加筋对软基位移场的影响.计算结果表明:土工格栅能较大地减小软基路堤的侧向位移、减小不均匀沉降和堤外隆起,在一定程度上减小路堤的最大沉降.研究结果对软基上路堤加筋处理有借鉴意义.
The finit element method is used to analyse the influence of reinforcement to displacement field of soft subgrade by way of comparing reinforced embankment with unreinforced embankment.The calculative results indicate that geogrids can effectively decrease lateral,asymmetrical and heaved displacement,and also can reduce the vertical settlement to a certain extent.The research result is of certain reference value for engineering of reinforced embankment with soft foundation.
