摘　　要：为研究川气东送二线枣阳-宣城联络线天然气管道工程对穿越牛屯河河势及水文情势的影响,采用洛赫京河床稳定性系数公式、MIKE 11 NAM流域洪水模型、Lacey等冲刷公式以及《水工结构有限元分析系统》堤防渗流场计算程序等方法 ,分析河道演变情况、穿越河段设计流量、设计洪水位以及工程建成对河道行洪、冲刷、河势、排涝、堤防及岸坡稳定性的影响。结果表明,管道工程对河道防洪无明显不利影响,可为工程设计及河道管理提供科学的依据。In order to study the impact of the second Sichuan Gas Eastward Transmission Line Zaoyang-Xuancheng interconnection line natural gas pipeline project on the river flow and hydrological situation across the Niutun river,the Lokhkin riverbed stability coefficient formula,MIKE 11 NAM basin flood model,Lacey and other scour formulas,and the levee seepage field calculation program of the"Finite Element Analysis System for Hydraulic Structures"were used to analyze the river evolution,the design flow of the crossing river section,the design flood level,and the impact of the project completion on the river flow,scour,river flow,drainage,levee and bank slope stability.The results show that the pipeline project has no obvious adverse effect on river flood control,which can provide a scientific basis for engineering design and rivermanagement.
