Examples
- 1 . six rules of studying out the assessment index and the method of founding the comprehensive safety assessment structure system of the levee engineering are discussed . also , the design of safety evaluation aggregation of the system is lucubrated and the fourth - class divisional method of safety grade is ascertained
主要研究内容如下： 1 、针对河道堤防工程特点，拟定了构建堤防工程安全综合评价结构体系的原则；探讨了堤防工程安全综合结构体系的建立方法，并对安全评价集及安全综合评价方法等内容进行了深入研究，确定了堤防工程安全评价的四级划分法。 - The theory and method , such as analytic hierarchy process , grey system and so on , together with the knowledge of embankment engineering , are introduced into the thesis , which performs relatively detailed study on method of comprehensive safety assessment , synthesis assessment structure system , method of measuring assessment index and the precautionary mode of safety evaluation of the levee engineering
本文以河道堤防工程为主要研究对象，应用层次分析、灰色系统等理论和方法，对堤防工程的安全综合评价方法、综合评价结构体系、评价指标度量方法以及堤防工程安全预警模式等方面内容进行了深入的分析研究。 - This thesis concludes the flood control situation , engineering measures and the situation of optimal dispatch method . it studies flood control engineering system , which is composed of flood prevention reservoir , river course dyke and natural detention basin , and the relationship between various flood engineering measures according to the composition and characteristics of the flood control engineering of the middle - lower reaches of beijiang . it suggests the objective function based on the least flood loss and the optimal dispatch strategy structure of the middle - lower reaches of beijiang bound with the requirements of the flood gradual progress equation combined with hydrology and hydraulics
本论文总结了我国防洪情势、防洪工程措施及其优化调度方法研究的现状；针对珠江流域北江中下游防洪体系的组成及其防洪工程的特性，研究由防洪水库、河道堤防和天然滞洪区共同组成的防洪工程体系中各防洪工程措施之间的关系；提出了以洪灾损失最小为目标函数、以水文学和水力学相结合的洪水演进方程等要求为约束条件的北江中下游防洪体系优化调度策略框架。
