| 摘 要： | 以往的涵洞长度计算方法都是从平面上着手分析、考虑并找出其计算公式的。但由于影响涵洞长度的因素较多,并且各因素间相互制约,使得有的方法公式推导过程较为繁琐,有的计算结果误差偏大。为此,本文利用空间解析方法,使涵长计算公式的推导过程极为简便、直观,进而找出可能情况下的涵洞长度准确表达式,并给出计算实例,以便在设计中参考使用。

| Abstract: | In previous method for calculating culvert length, first, the plane is analysed, then the calculation formula is found out. In this way, the derivation processes of formula are complex and the error in calculation result is great because there are lots of factors influencing on culvert length and the factors also restrict each other. This paper presents simplified and accurate calculation formula of calculating culvert length by adopting space analysis method, gives an example of calculation, for reference to the design. |
