摘要
本文采用河道一维水力计算软件V1.0,以绕阳河下游盘山县段为研究对象,通过对地形图处理及选取合适的参数,分别对不同行洪宽度工况下的水位进行计算分析,综合对比分析后确定了绕阳河不同分段清障的行洪通道宽度,从而确定合理的清障范围,可为同类型大中型河流清障提供决策依据和技术参考。
In this paper,one-dimensional channel hydraulic calculation software V1.0 is adopted,and the Panshan County section of the lower reaches of the Raoyanghe River is taken as the research object.By processing topographic maps and selecting appropriate parameters,the water level under different flood flow width conditions is calculated and analyzed respectively.After comprehensive comparative analysis,the flood passage widths of different sections of the Raoyanghe River are determined,so as to determine a reasonable obstacle clearance range.It can provide decision-making basis and technical reference for the same type of large and medium-sized river clearing.
