combination of loads meaning in English
荷载组合
Examples
- Introduced by prestressed pier in the gate of spillway in xiao xia hydroelectric power station , the text reasonably established 3 - d finite elements mechanic model by the advanced finite elements popular in the world which can expediently impose tension of anchor funicular at its place . it also considered possible diversified combination of loading , and indicated that the effect of its prestressed action is fruitful compared with its conventional counterpart by study of mechanic calculation in comparison . as a result , it vastly improved burdening state of pier . by analysis of 3 - d finite element method , it also gained the stress result indifferent boundary conditions such as breast wall joint support and fixed support , and the displacement result in diversified loading combination . those results gained the instructive and reference value in design of prestressed pier
本文结合黄河小峡水电站泄洪闸预应力闸墩这一工程实践,采用国际上已成熟的有限元方法,合理地建立了预应力闸墩的三维有限元模型,该模型可方便地按预应力锚索的点位施加锚索预张拉力,考虑了可能发生的多种荷载工况组合,并与无预应力闸墩结构进行了对比分析研究,指出其预应力效果是明显的,可以大大改善闸墩结构的受力状态,通过三维有限元分析,还得到了胸墙简支、固端不同情况下的应力成果和各荷载下的位移成果,这些成果的取得对预应力闸墩的设计具有一定的指导和参考价值。
