我国在世界上首次提出"主动降温、减少传入地基土的热量、保证多年冻土的热稳定性，从而保证修筑在上面的工程质量的稳定性"的青藏铁路工程设计原则，创造性地采取了解决冻土施工难题的相应对策：对于不良冻土现象发育地段、线路尽量绕避；对于高温极不稳定冻土区的高含冰量地质，采取"以桥代路"的办法；在路基施工中采用了热棒、片石通风路基、片石通风护道、通风管路基、铺设保温板等多项设施，提高冻土路基的稳定性；在桥涵基坑、挡水埝基槽开挖中，创造性地应用了单齿破碎器，解决了冻土开挖难题；在桥涵工程施工中，采用了耐久性混凝土，采用了三步养生法，保证了结构物内实外美。

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。
