| 摘 要： | 针对土工格栅嵌锁力提出了一套简化的理论计算方法。通过对碎石填料和格栅作用模型的简化处理,给出了一种格栅与填料颗粒的单元嵌锁模式,并通过对该嵌锁模式下的填料颗粒的两种运动趋势—平移和转动进行讨论和分析,推导了不同条件下格栅的极限拉力,得出了最终的单元嵌锁力。

| Abstract: | A simplified theoretical method to predict the interlocking forces in the geogrid reinforcement is proposed in this paper.Through a simplified approach of the aggregates and geogrid interactions,a unit interlock mode is proposed to simulate the two relative movement modes between the soil backfill and the geogrid.These two basic movement modes are: translation and rotational move.The ultimate tensile forces of the geogrid as well as the unit interlocking forces are derived. |
