| 摘 要： | 依托郑州至洛阳高速公路改建工程，采用数值模拟的方法研究高填土涵洞垂直土压力分布规律。发现高填土涵洞涵顶存在垂直土压力集中现象，土压力集中系数随填土高度的增加逐渐增大，当涵顶填土达到一定高度后逐渐稳定并略有减小.

| Abstract: | Based on reconstruction project of Zhengzhou-Luoyang Expressway, this paper uses numerical simulation method to study the distribution law of vertical earth pressure of high fill culvert. The result shows that vertical earth pressure concentrates at the roof of high fill culvert, and the concentration factor of earth pressure is gradually increasing with the increase of filling height. When the filling reaches a certain height, the earth pressure is stable and has a slight decrease. |

| Keywords: | high fill culvert vertical earth pressure concentration factor |
