几种关于高填方涵洞涵顶土压力计算方法的探讨

Discussion on several culvert top earth pressure calculation methods of the high fill culvert

在道路设计和建设中,由于道路线形和降低造价的需要,高填方涵洞的设置越来越多。为了安全可靠经济地设计涵洞,正确的计算涵顶土压力就非常必要。文章通过探讨几种高填方涵洞涵顶土压力的计算理论和计算方法,并将这几种计算方法的计算结果互相对比,得出这几种方法的体会。

In the design and construction of the road, as a result of the need of road alignment and reducing cost, more and more high fill culvert are setted.In order to ensure the safe reliable and economic design of culvert, correct calculation of culvert top earth pressure is very necessary.This paper discusses several kinds of high fill culvert top culvert earth pressure calculation theories and calculation methods, and compares the calculation results of several calculation methods with each other, different experience of these methods are concluded.
