Based on the principle of variation of earth pressures on the culverts under different conditions, including topography, span of culvert, density of fill and the type of structure, and the property of arching action above the culvert, a nonlinear earth pressure theory for culverts beneath high fill is presented, the theory suggests the earth pressure on the culverts beneath high fill can be calculated with the formula σ=ξγH〓 as the fill up to higher height.
把这种方法与其它地下洞室的土压力计算理论进行的对比分析结果表明,非线性土压力理论考虑了填土达到一定高度时在涵洞上方产生的拱效应以及土拱的不稳定性特点,其计算的土压力明显低于不考虑拱效应的低填方涵洞土压力计算值,但高于具有稳定土拱效应的地下洞室土压力理论得到的土压力。

The test results show the principle of variation of pressures on culverts beneath high fill is similar, it is that, even if the embankment is filled up to a higher height, the earth pressures can still partly transfer to the top of culvert, as a result the pressures on the culvert increase nonlinearly with the variation of height of fill and further the pressures are obviously lower than theoretical value by σ=γH.
模型试验和数值模拟计算结果表明,当填土达到一定高度后,高填方涵洞上方将产生明显的拱效应,但由于涵洞填土为破碎的岩土,其拱效应与岩石中开挖洞室上方的拱效应不同,高填方涵洞上方填土产生的"土拱"效应具有不稳定的特点,表现为随着填土高度的增加仍有部分土压力传递到涵洞上,涵顶土压力随填土高度成非线性增加。
