摘要
安徽省天然气宣城-宁国-黄山支线(宁国至绩溪段)工程穿中津河过程中,由于水文气象资料、河道资料较为缺失,穿越工程洪水影响分析较为困难。本论文,利用流域面积类比法与安徽省“84”洪水计算法计算得出相应频率状况下洪峰流量,指导冲刷、渗流分析,利用实测数据进行河道稳定等计算,最终得出管道穿越对河道无实际影响,同时洪水对管道无干扰。
During the process of the natural gas Xuancheng-Ningguo-Huangshan branch line(Ningguo-Jixi section)in Anhui Province,due to the lack of hydrometeorological data and river channel data,it is difficult to analyze the impact of flooding through the project.In this thesis,the basin area analogy method and the“84”flood calculation method in Anhui Province are used to calculate the flood peak flow under the corresponding frequency conditions,guide the analysis of scouring and seepage,and use the measured data to calculate the stability of the river channel.Finally,it is concluded that the pipeline crossing has no actual effect on the river channel.The impact,while the flood does not interfere with the pipeline.
