| 摘 要： | 堤防工程安全受洪水、地震、堤身土质及堤基结构等多种因素影响,且其作用机理复杂,一旦失事危害巨大.将突变理论引入堤防工程安全评价中,根据突变评价原理,建立了堤防工程安全综合评价指标体系,参照大坝安全评价标准,结合堤防工程特点,建立了堤防工程安全等级划分标准,利用突变评价的归一公式计算了北江大堤石角堤段设计洪水情况的安全评价指标值,根据等级划分标准,从计算结果分析得知该段堤防在设计洪水工况下安全性较高,为堤防工程安全管理提供科学依据.

| Abstract: | The safety of dike is affected by flood,earthquake,the soil of the levee,the structure of the levee foundation and many other factors;moreover,its mechanism is rather complex.Because any accident of it will result in a huge catastrophe,the safety of levee construction has been a matter of common concern and a hot research topic in the field of engineering.The mutation theory is introduced to the safety evaluation of embankment.A comprehensive assessment indicator system of the safety of dike,based on catast... |
