辽河主要控制站防汛特征水位研究

Research on the flood control characteristic level in liaohe river flood control stations

针对辽河干流水文特征、河道特性及防洪特点,探讨了防汛特征水位确定的原则、机理、方法和标准,以年最高水位、最大洪峰流量频率作为警戒水位的基本依据,建立计算模型和检验方法,并从辽河防护对象、洪水特性、堤防工程防御标准和社会经济条件等综合分析,提出辽河干流主要控制站警戒水位。同时,根据堤防工程设计,确定保证水位。

This paper put forward the mechanism,principles,standards and methods deciding the water level on the flood control through researching the characteristics of hydrological and flood control of Liaohe main stream.Taking the highest water level and biggest peak discharge as warning level,the computation module and verified method are set up.Based on the analysis on characteristics of flood,control standards of the embankment engineering and economic condition,the warning level of main stream of Liaohe River i...
