折腰沟管道悬索式跨越结构静态强度分析

Static Strength of Oil Pipeline Spanning Over the Zhe-Yao Ditch

在考虑自重、风载等载荷的作用下 ,对马惠宁输油管道折腰沟管道跨越结构的原设计状况进行了分析 ,在考虑沟坡坍塌、悬索及抗风索锈蚀和松弛等情况下 ,对结构的位移、应力等进行了有限元计算 ,对结构的静力安全性进行了评估 ,并给出了目前该管道跨越结构安全状况的评估结论 。

The paper sums up the natural environment, topography, landforms, geology, hyd rology and meteoro logy for MaHuiNing Oil Pipeline lacated at the loess plateau . In this paper, the problems ought to the geology at loess plateau are put froward. Some effective measures and suggestions against the geological problems are presented. lems are presented.
