| 摘 要： | 采用室外路面试验研究路面流的流态,在三种路面条件下,进行三种坡度,五种流量的放水冲刷实验,观察流速、水深和流态的变化。试验结果表明,平均流速和水深受路面粗糙度、坡度和流量共同影响,流量的影响最大,坡度和路面粗糙度影响较小;流态则只受流量的影响,坡度和路面粗糙度几乎没有影响。

| Abstract: | Though the experimental study outside the road surface stream flow observes the changes of velocity,water depth and flow pattern on the pavement under the condition of three kinds of pavement,three kinds of slope,five kinds of flow washout experiments.The experimental results show that the average flow velocity and water depth are affected by road roughness,slope and flow together and the biggest influence is flow,the influence of slope and the road surface roughness is smaller.Flow regime is only affected by flow,slope and road surface roughness have little impact on it. |
