摘要
上海地处长江三角洲前缘,上海海塘分处长江口及杭州湾北岸。在径流、风潮等因素影响下,海塘堤前滩变化会较为复杂,若堤前的滩涂不断受到冲刷侵蚀,滩涂后退,危及海塘和防汛安全,故采取科学合理的保滩措施,是确保海塘及防汛安全的重要手段。为此,梳理了上海常见的保滩类型,分析保滩型式的保滩机理和适用条件,为本市保滩工程选型和设计提供参考。
Shanghai is in the front of the Yangtze River Delta and Shanghai seawall is located in the Changjiang Estuary and the North Bank of Hangzhou Bay.Under the influence of runoff,wind tide and other factors,the front beach of the seawall dike will change more complicatedly.If the beach in front of the dike is continuously eroded,the beach will retreat,endangering the safety of the seawall and flood control.Therefore,taking scientific and reasonable beach protection measures is an important step to ensure the safety of the seawall and flood control.This paper reviews the common types of beach protection in Shanghai and analyzes the mechanism and applicable conditions of beach protection,providing reference for the selection and design of beach protection projects in Shanghai.
