高速公路涵洞方案比选研究

The Study on Expressway Culvert Scheme Comparison

首先介绍了各类涵洞的优缺点及适用性,进而紧紧抓住涵洞设计流量与泄洪能力之间的关系,采用高速公路建设中较为合理的水力计算公式,对常见尺寸的涵洞泄水流量进行了计算,最后给出了一定设计流量范围内,涵洞方案比选的最优结果,为广大设计人员提供参考。

First this paper introduces the advantages and disadvantages and applicability of various kinds of culverts,and finds out the relationship between culvert design flow and flood carrying capacity. With the relatively reasonable hydraulic computation formula during expressway construction,the common culvert releasing discharge is calculated,the optimal result of culvert scheme comparison within a certain design flow is given finally,which can provide a reference for designers.
