高填方穿坝涵管顶土压力变化规律数值模拟研究

Numerical simulation of earth pressure variation on top of high fill culvert

对高填方涵管而言,其顶部的土压力对涵管的设计和结构稳定具有重要意义。文章以龙王庙卧虎水库工程穿越坝体涵管为例,利用数值模拟的方法研究了高填方穿坝涵管顶土压力变化规律,得到的结论对具体工程的涵管设计具有一定的借鉴意义和价值。

For high fill culvert,the earth pressure at the top of the culvert is of great significance to the design and structural stability of the culvert.Taking the culvert pipe through the dam of Wohu Reservoir Project of Longwangmiao as an example,this paper studies the variation law of earth pressure on the top of the culvert pipe through the dam with high fill by using the method of numerical simulation.The conclusion has certain reference significance and value for the design of the culvert pipe in specific projects.
