Shallow buried-tunnelling method was used in the construction of high discharge pressure culvert for the first time and developed a new construction method in urban water distribution project.
在设计中将浅埋暗挖技术首次应用于大流量有压输水暗涵，进一步拓展了适用于城市输水工程的工程技术手段。

Then we develop the discharge coefficient formula in the culvert.
并提出了计算了泄水涵洞流量的流程图。
