摘　　要：在进行理论分析和水槽试验的基础上 ,得出了水流作用下充砂袋失稳流速参数的表达式 .据此 ,开发研制出了低价高摩擦性能的土工织物防汛袋 .防汛袋的老化试验表明 ,大气曝露 6个月后 ,防汛袋的强度几乎丧失 ,而置于仓贮或水中 ,则强度几乎不变 .Based on theoretical analyses and flume experiments, an expression of destabilizing flow velocity for filled sandbags under the action of water flow is given. According to the expression, a kind of low price geotextile sandbag with comparalively high friction coefficient is developed. And the aging experiments of bags indicate that the sandbags almost lose their entire strength after they are exposed in air for six months, but their strength hardly falls when placed in store or under water.
