摘要
通过对辽河干流河道险工全面考察,河道险工成因分析以及河道演变分析结果,分别采用马卡维耶夫法、平滩水位法、造床流量保证率法、主汛期月平均流量法对造床流量进行了计算;根据历年主槽平均宽法、经验公式法、造床流量下现状河道水面宽法的计算,同时充分考虑各河段河道特点、上下游协调统一,并为河道的演变发展预留一定空间,综合确定了辽河干流各河段整治宽度;分别针对辽河两岸岸坎-缓坡和陡坡,提出了河道险工综合治理技术,为辽河干流防洪工程体系提供技术支持。
Through a thorough investigation and cause analyses on the critical Levee sections of the Liaohe River, and the evolution analysis of the water courses, the Makovieve method, the bankfull level method, the guaranteed rate of dominant discharge method and the main flood season average monthly flow method were used to calculate the river dominant discharge, respectively. The regulation river width was determined based on the calculations using the main channel average width of previous years method, empirical formula method and the water course width under current river dominant discharge method, full considerations of the characteristics of each river section, the coordination of up-and down-streams, as well as leaving space for the evolution of the river. With regard to the both banks gentle or steep bank, a comprehensive governance technology on critical levee section was proposed, which could provide technical supports to the flood control system of Liaohe River.
