摘要
采用FLAC对土工格栅加筋路堤不同铺设位置进行数值模拟,结果显示土工格栅加筋路堤铺设于底部效果最优,理论验证表明该模拟结果具备合理性。格栅材料、路堤材料、填土高度、过渡段模量比和格栅铺设范围是加筋土路堤的五个影响因素,对改善坡降差的效果有不同的影响。
By using FLAC to numerically simulate different laying position of geogrid reinforced embank- ment, it is showed that the optimal result is to lay the geogrid reinforced embankment on the bottom, which has been proved reasonable by theoretical verification. Grid material, embankment material, filling height, transition section modulus ratio and grille laying range are the five influencing factors of reinforced embankment with dif- ferent gradient difference improvement effects.
