为解决冲刷引起的崩岸问题,结合土力学和水力学原理,提出了崩岸防治新措施——模袋排帘。通过室内水槽模型的含沙水流试验,测量泥沙冲淤地形变化,对所提出的模袋排帘的功效进行了直观的验证。结果表明:模袋排帘结构形式能有效调整近岸坡水流结构;透沙窗的设置,适应河流悬沙分布特征,实现了局部淤积、稳定岸坡地形的目的;大大降低岸坡上的排体覆盖率,经济成本得到削减,且施工方便。
In order to solve the problem of bank collapse caused by scouring, a new measure for prevention and control of bank collapse was put forward, combining with soil mechanics and hydraulics theory. Through the sediment flow test of the indoor sink model, the change of sediment erosion and sedimentation was measured, and the effectiveness of the proposed mold bag curtain was verified visually. The results show that: the structure of mold bag curtain can effectively adjust the water flow structure of the near bank slope; the setting of the sand traversing window can adapt to the distribution of suspended sediment in the river and achieve the purpose of partial silting and stabilizing the slope topography; Body coverage, economic costs have been reduced, and the construction is convenient.
