Shallow buried-tunnelling method was used in the construction of high discharge pressureculvert 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。

The result involves the earth pressure on the top of culvert, the lateral earth pressure and the displacement of the earth with the different height of backfill.
涵顶垂直土压力系数随回填土高度的变化为先增后减的趋势； 填土中最大位移点随填土高度而变等。
