【摘要】 综合分析海堤遭受的内因与外因、人为与自然、结构与水文等因素作用和海堤失效模式,在分解分析法对海堤安全因素进行分类基础上,基于破坏路径法对影响海堤安全的主要因素进行识别,进而提出海堤安全防御刘象。结果表明:1)海堤工程系统存在越浪或漫溢、滑动和塌陷、渗透变形、坡面冲刷、交叉建筑物及其他形式失效等五种失效模式;2)基于破坏路径分析各破坏模式下的影响因素,得出影响海堤安全的主要因素为潮位、风速、地震和降雨等4种,也即为海堤主要防御对象。更多还原

【Abstract】 Comprehensive analyzes of failure models of sea-dike in multi-factors action,such as internal and external,human and natural,structure and hydrology,and other factors,and suggests systematically identifying sea-dike factors by the decomposition analysis method and detailed identifying the main security factors based on failure path analysis(FPA).The main fruits as below:1)There are five types of failure models for sea-dike engineering system,overtopping or overflow,sliding and sink,seepage deformation,intersect structures and others failure;2) The main security factors are tidal level,wind velocity,seismic and rainfall,or defense objects of sea-dike.更多还原
