生态袋是柔性生态边坡工程材料，被广泛地应用于河湖边坡防护、矿区的恢复、铁路和公路的边坡防护、屋顶绿化等方面，是治理水土流失、改善河湖健康的一种生态友好型边坡防护材料。目前人们对生态袋护坡水力特性的研究很少，制约了生态袋在边坡防护中的应用。本文采用量纲分析方法提出了生态袋护坡在波浪作用下，生态袋内土壤颗粒损失的计算公式，并利用试验方法分析了生态袋护坡在波浪作用下的损失规律。研究表明，当波浪冲刷时间用无量纲时间表示时，不同波浪周期情况下，生态袋的浪蚀规律一致。生态袋的损失率随波高呈非线性变化，在波浪较大的情况下，在生态袋的植被生长起来之前，应注意生态袋护坡的防护，以避免生态袋岸坡的坍塌。

Geotextile sandbag is a kind of flexible eco-friendly revetment material, which has been widely used in slope protection of rivers and lakes, reclamation of mining areas, slope protection of highways and railways,and green roofs et al. The hydraulic characteristics of the sandbag structures are less studied,lim-iting its application in the riverside or shoreline protection. The dimensionless erosion loss formula of the sandbag structures is deduced based on the dimensional analysis, and the wave erosion characteristics of the sandbag structures are experimentally investigated. The experiments show that when the wave erosion pe-riod is expressed with dimensionless value,the wave period has no effect on the wave erosion of the struc-tures, and the wave erosion loss rate of the sandbag structures has a non-linear relation with the wave height. Therefore,the sandbag structure should be properly protected from the wave erosion before the vege-tation growth of the seeded bags under the condition of large wave.
