本文系统介绍了斜拉空间桁架竖向地震反应的分析理论与方法、详细分析了斜拉空间桁架结构在静力和竖向地震作用下的受力性能，主要内容包括：利用通用有限元软件ANSYS9.0计算了斜拉空间桁架在静力和竖向地震作用下内力及自由端位移分布规律并得出地震内力系数与节间位置、预应力以及斜拉索高度之间的函数关系；详细分析了斜拉索中施加的预应力以及斜拉索高度的变化对于该种结构内力及自由端位移的影响并提出了斜拉空间桁架的临界预应变概念，进而得到了自由端位移与初始预应变以及斜拉索高度的函数关系，即：△=-(40h+2180)ε+9.8；分析了该种结构的动力性能，并指出：在时域内采用直接积分法计算该种结构的动力响应时，应该考虑采用不引起振幅率减小的Newmark-β法，以保证高阶模态响应的贡献仍然保留在响应中而不致于被忽略。

The test results show that, the drag bar pull and efficiency coefficient is increasing with the wheel width and diameter. The draw bar pull increased with the rug height, but the efficiency coefficient reduces when the slip radio is bigger than 20%. The draw bar pull and efficiency coefficient will reduce with the rug distribution incereases when the rug distribution is more than 20%.

The fruits of research in the thesis as follow:(1) The principle of variation of earth pressures on the culverts beneath the high fills are investigated in the thesis.

论文通过模型试验和数值模拟计算，研究了狭窄沟谷地形、宽坦沟谷地形、岸坡设涵和坡脚设涵四种边界条件下的高填方涵洞土压力随填土高度变化的规律，研究结果表明，在各种边界条件下，高填方涵洞涵顶土压力变化规律相似，当填土达到一定高度后，仍有部分土压力传递到涵顶上，使高填方涵洞的土压力不随填土高度成线性增加，土压力呈非线性变化，高填方涵洞的土压力明显低于理论土压力σ=γH计算值。

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。
