摘　　要：以先进的地表水流流场模拟软件SMS为平台,以金沙江陈家溪河段为研究对象,探讨固定边界水流流场数值模拟的步骤与过程,通过与实测值的对比发现,所建模型大部分监测点的水位、水深、流速的计算误差都在5%以下,表明此金沙江河段数学模型计算精度较高,可为固定边界水流研究提供借借鉴.Many rivers in our country need further development and utilization. Using the advanced SMS simulation software of surface flow field as a platform, the steps and process of the numerical simulation for fixed boundary flow field are dis- cussed in the this paper, taking Chenjiaxi section of Jinsha River as the research object. Compared with the measured val- ue, the calculation errors in water level, water depth and flow velocity from the most monitoring points of the established model are below 5%. It proves that the mathematical model for Jinsha River is of high computational accuracy, providing reference for fixed boundary flow research.
