基于仙农熵理论的河相关系

在河流动力学理论研究中,已有的河相关系式大多是经验半经验性质的,往往不能明确地表达因素的影响,应用时具有很大的局限性.在能量均衡关系的基础上,利用仙农熵的理论,对影响沙质河床稳定河相关系的因素进行了探讨.通过理论分析,认为在取得所测河段上下边界测点相关资料后,用最大熵原理和变分法可以推导出稳定的河相关系式,最后通过试验对所得公式验证其合理性,认为其在计算试验区间任何时刻河相关系系数,均得到较好的吻合结果.

Hydraulic Geometry Based on Shannons Entropy Principle

Among the river dynamics theory researches,the most of relations of hydraulic geometry are with the characteristic of experience and semi-experience,the effect of hydraulic factors on the hydraulic geometry was not clearly explained and discussed,and their applications were widely limited.On the basis of conservation of energy,the paper uses Shannon entropy theory to explain and discusses the influence factors dealt with the sandy river bed stability,the concept of Shannon entropy is considered for setting ...
