摘要: |
涨潮沟圈围施工顺序及龙口选址关系到施工期堤线滩势稳定和工程成败.以青草沙水库工程为实例,分析了潮汐河口中涨潮沟特殊地貌的形成及维持的机理,介绍了以大型涨潮沟为对象的圈围工程的围堤实施顺序和龙口选址问题的研究技术路线,通过数模物模分析水动力特性,结合施工组织等因素,提出了先高滩后深槽和龙口设在涨潮沟中的结论,揭示了同类工程的一般规律,并经实践成功检验. |

Abstract: |
Construction procedure and closure gap site selection for the dike-closing project in a large flood channel play a decisive role in the beach stability and success of the project.According to Qingcaosha reservoir research and practice,the mechanism of the shape formation and thestability of the flood channel in tidal estuary is analyzed,the research route for the construction procedure and the closure gap site selection of the dike-closing engineeringis introduced.Based on the study of river hydrodynamics b... |
