摘　　要：随着码头护岸边坡的发展,填筑体加筋参数优化研究对提升边坡稳定性越来越重要。通过对边坡填筑体加筋的室内模型试验与数值分析,探讨了加筋参数对边坡稳定性的影响,得出了加筋参数综合优化组合。研究结果表明:加筋对土体位移有约束作用,埋置深度对土体位移影响最大,过大的竖向土压力会造成土工格栅的侧向变形大,甚至破坏。土工格栅埋置比固定后,土体下沉量和加固深度趋于稳定,为防止格栅位移过大导致破坏,应选择较小间距。对加筋参数的优化可以有效地提高码头护岸边坡的稳定性,减少工程风险。With the development of the wharf revetment slope,the study on the optimization of reinforcement parameters of filling body is more and more important to improve slope stability.Through the indoor model test and numerical analysis of the reinforcement of the slope filling body,the influence of reinforcement parameters on slope stability is discussed,and the comprehensive optimization combination of reinforcement parameters is obtained.The results show that reinforcement has a restraining effect on soil displacement,and that burial depth has the greatest influence on soil displacement.Excessive vertical earth pressure will cause the large lateral deformation of the geogrid,or even damage.After the burial ratio of the geogrid is fixed,soil subsidence and reinforcement depth tend to be stable.In order to prevent the damage caused by the excessive displacement of the geogrid,smaller space should be selected.The optimization of reinforcement parameters can effectively improve the stability of the wharf revetment slope and reduce the engineering risk.
