摘　　要：为了增强堤坝的抗溢流侵蚀能力,防止洪水决堤,本文对土工合成加筋土堤坝在各种条件下的性能进行了深入研究,并探讨了土工格栅层对堤坝渗透性能的影响。研究结果表明,选择合适尺寸的土工格栅对现有大坝进行局部加固是一种切实可行的方法,利用土工合成材料加固防洪堤可显著增强堤坝的安全性和稳定性,降低溢流侵蚀的风险,进而延长防洪堤的使用寿命,该研究为防洪堤设计提供了一定的理论依据和参考。In order to enhance the anti-overflow erosion ability of the embankment and prevent the flood from breaking the embankment,the performance of the geo-composite reinforced earth embankment under various conditions is deeply studied,and the influence of the geo-grid layer on the permeability of the embankment is discussed.The research results show that it is a feasible method to select the appropriate size of the geoglass to strengthen the existing dam locally.The use of geosynthetic materials to strengthen the levee can significantly enhance the safety and stability of the levee,reduce the risk of overflow erosion,and then extend the service life of the levee.This study provides a certain theoretical basis and reference for the design of the levee.
