拱涵位移和垂直土压力的数值模拟

The numerical simulation of arch culvert displacement and vertical soil pressure

通过数值模拟,对高填方拱涵的土压力和位移进行了数值分析,确定了高填方拱涵的土压力分布规律和位移规律,指出涵顶土压力呈非线性分布特征,不同于现行《公路桥涵设计通用规范》中的土压力线性分布假定。

Through the numerical simulation,this paper made numerical analysis on soil pressure and displacement of high fill arch culvert,de-termined the soil pressure distribution rules and displacement rules of high fill arch culvert,pointed out the culvert top soil pressure had nonlin-ear distribution feature,different from soil pressure linear distribution of current Highway Bridge and Culvert General Design SPeciFication.
