查询词典 variation factor

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。
