摘要
通过全断面平均法、有限单元平均法、有限单元徽分法计算水流流量模数,找出各种方法之间的误差。得出将宽浅断面改造成滩槽高差显著的复式断面是极为有利的结论。
The differences between different calculation methods for hydromodulus, i.e. whole section average method, finite element average method and finite element differential method are found out and the concusion that it is quite advantageous to renovate broad shallow section to compound section of obvious shoal-channel elevation difference is drawn.
