摘要
咯河(德吾录河)河道长度为68.4 km,已治理河段41.57 km,合作市段已安排实施项目治理河长约5.95 km,有防洪任务河段基本治理达标,剩余20.88 km河段未建设,文章以合作市咯河未治理段河道为例,分析河道存在的问题,进行水面线推算方法研究,并通过河道稳定河宽计算、河道纵横稳定计算、河相系数计算来进行河道演变分析及两岸绿化措施建立生态绿化带的基础上,提出未治理段河道的治理方案。
The length of Luohe River(Dewulu River)is 68.4 km,with a treated section of 41.57 km.The cooperative city section has arranged for the implementation of a project to control the river length of about 5.95 km.The river section with flood control tasks has basically reached the standard,and the remaining 20.88 km of river section has not been constructed.This article takes the untreated section of the Luohe River in Hezuo City as an example to analyze the problems existing in the river channel and conduct research on the calculation method of water surface profile.It conducts river evolution analysis through the calculation of stable river width,vertical and horizontal stability,and river phase coefficient.Based on the establishment of ecological green belts through greening measures on both banks,it proposes a treatment plan for the untreated section of the river.
