摘要
土工格栅由于强度高、弹模高、蠕变低、与土体嵌锁作用明显,被广泛应用于提高路基、堤坝、边坡以及挡土墙的稳定性。开展土工格栅-填料相互作用机理研究可以深入揭示土工格栅对填料的加固机制。本文在广泛查阅和搜集资料的基础上,对近年来土工格栅-填料界面特性的试验研究、理论研究和数值模拟分别进行总结分析,并对未来研究发展方向做了展望,希望对加筋土的研究发展起到一定的指导作用。
Geogrid is widely used to improve the stability of subgrades,embankments,slopes and retaining walls due to its high strength,high modulus of elasticity,low creep and obvious interlocking effect of soil.The interaction mechanism between geogrid and backfill at the interface is a key basis for understanding the mechanism of geogrid reinforcement.On the basis of extensive access and data collection,the experimental research,theoretical research and numerical simulation of the interface characteristics of geogrid-backfill in recent years are summarized and analyzed respectively,and the prospect of future research and development is prospected.
