摘要
三峡蓄水后,持续清水下泄,可能导致下游河道洲滩持续冲刷后退,洲滩守护成为长江中下游航道整治的重要措施;同时护滩带结构遭到水毁的几率大增,护滩结构亟需改善。水槽试验表明,四面六边透水框架作为一种新型护滩技术,减速落淤效果十分明显。四面六边框架群与护滩带相结合,能够增强护滩工程的稳定性,改善护滩带边缘破坏情况,在实际应用中取得了较好的效果。
After impoundment of the Three Gorges reservoir,clean water coming from the reservoir may lead to continued erosion of the sandbars and beaches in the middle and lower reaches of the Yangtze River during a long period.So,to protect the sandbars and beaches from being eroded became an important measure of channel rectification.Meanwhile,the structures of beach protection will be damaged more easily,and the traditional structure must be improved.Flume tests show that the effect of scour prevention and sedimentation promotion of beach protection is obvious for tetrahedron penetrating frame groups as a new technology.Through arranging the tetrahedron penetrating frame groups and protective belt of beach,we can enhance the stability of beach protection project,and improve the damage of the edge of protective belt of beach.The technology has been applied successfully to some projects of channel rectification.
