阐述了 HEC -RAS 及 MIKE11软件的计算原理，并对2种软件数值仿真成果进行了对比分析。结果表明：采用 HEC -RAS 软件计算的水位成果相对 MIKE11软件计算的水位成果稍小；HEC -RAS 软件计算的流速成果较MIKE11软件计算的流速成果偏大。对不同软件的数值仿真成果分别与河工模型试验成果比较，发现仿真成果与试验成果的水位差值和流速差值沿程变化基本一致。在山区天然河道水面线推求时，结合工程实际选择计算软件，对河道规划设计具有一定的应用意义。

Elaborated the principle calculation of HEC -RAS software and MIKE11 software ,and compared with two kinds of software of the numerical simulation results.The results have showed that HEC -RAS software calculated water level result was smaller than MIKE11 software.but the velocity result of the HEC -RAS software to MIKE11 software calculation results higher.Through compared different software numerical simulation results with respectively physical model test results,found that the simulation results with the experiment results of water level and velocity D -value variation were consistent along the river.In mountainous area of natural river computation,the in -situ test consolidation calculation software of choice should be on the basis of engineering practice,therefore the channel planning and design has a certain guiding significance.
