本文根据实验资料验证了在水深很小情况下,计算路面缘石街沟泄流量时谢才—曼宁公式的适用性;并根据实验资料对高等级公路路面排水中的缘石开洞截流入水口在各种情况下截流量大小进行了分析和研究,建立了截流量与主要影响因素间的定量关系。为工程设计提供了一个科学的设计计算方法。
Based on the experimental data, this paper verifies the applicability of the Xiecai-Manning formula when calculating the discharge of pavement curbs in the case of very low water depth. According to the experimental data, the opening of the curbs in the pavement drainage of high-grade highways is intercepted at the inlet In all cases, the size of the interception is analyzed and studied, and the quantitative relationship between the interception and the main influencing factors is established. For engineering design provides a scientific design calculation method.
