针对近年来最小二乘法用于马斯京根法出现的一种趋势,从流量演算法的水力学理论出发,剖析了马斯京根法进行洪水演算的原理,指出了马斯京根法中参数的物理意义。同时通过马斯京根法的理论解释,从理论上论证了康吉演算法推算具有衰减特性的洪水波运动必须满足的条件,指出了最小二乘法用于马斯京根法公式参数确定时造成的参数物理意义的模糊,并且该做法并不能从理论上保证该条件的成立以及可能出现的问题,所得结论愿与读者商榷。
Aiming at the trend of Muskingum method in recent years by using the least square method, this paper analyzes the principle of Muskingum method for flood calculation from the hydraulic theory of flow calculation method, The physical meaning of the parameters. At the same time, by means of the Muskingum method, the theoretic explanation is given to prove that the konjian algorithm must satisfy the condition of the damped wave motion. The least square method is used to determine the parameters of the Muskingum method The physical meaning of parameters is vague, and the practice does not theoretically guarantee the establishment of this condition and possible problems. The conclusion is ready to be discussed with readers.
