摘　　要：防汛抢险中常因分蓄洪区围堤非植物内护工程而出现险情误报、误判甚至失控状况,为达到分蓄洪区围堤同时满足外防洪与内防浪的双重目的,根据分蓄洪区围堤现状,结合历年的防汛抢险实际情况,分析了非植物内护工程对抢险、除险和堤防管理及生态的影响,风浪对内护堤段堤身的破坏能力和采用其他措施替代块石护坡防浪的可行性,认为分蓄洪区围堤内护工程应根据其防护重点、保护范围及保护对象,选择植物护坡或复合护坡,以防御分蓄洪后风浪对分蓄洪区内堤坡的冲刷破坏。In flood prevention and emergency rescue,there are often misreports,misjudgments and even out of con⁃trol due to non-vegetated internal embankment protection engineering in flood diversion areas.In order to meet the dual purposes of external flood prevention and internal wave prevention,according to the current situation of the embankment in the flood diversion areas,combined with the actual situation of flood prevention and emergen⁃cy rescue over the years,this paper analyzes the impact of non-vegetated internal protection engineering on emer⁃gency rescue,danger removal,embankment management and ecology,the destructive ability of wind and waves on the embankment body of the internal embankment section,and the feasibility of using other measures to replace block stone slope protection and wave prevention.It is believed that the internal embankment protection engineer⁃ing of the flood diversion areas should be based on its protection focus,protection scope and protection objects.Choose plant slope protection or composite slope protection to prevent the erosion and destruction of the embank⁃ment slope caused by wind and waves after flood diversion and storage.
