用宽顶堰理论检验法计算小桥涵设计流量

Calculation design rate of discharge of small bridge with broad crested weir theory

提出用宽顶堰理论检验法计算小桥涵洪水流量。该计算方法是通过实地调查桥前水深等资料 ,采用严密的宽顶堰理论推导 ,求得洪水流量 ,进而推求设计流量。本计算方法克服了很多不定因素 ,所以 ,其计算准确度高 ,很值得推广应用。

The text submit calculation flood rate of discharge of small bridge with broad crested weir thory.The method was adapt broad crested weir theory derivation to calculation flood rate of discharge and conjecture design rate of discharge through field investigate information of bridge.The method can surmount instability factor,so result has high precision.
