The wind sang in the taut weather-rigging, and blustered around Bush's ears as he stood on the starboard side of the quarterdeck, balancing to the roll as the roaring wind sent one massive grey wave after another hurrying at the ship; the starboard bow received the wave first, beginning a leisurely climb, heaving the bowsprit up towards the sky, but before the pitch was in any way completed the ship began her roll, heaving slowly over, slowly, slowly, while the bowsprit rose still more steeply.

布什站在右舷后甲板，在风浪中努力保持着平衡。一波波的灰色巨浪扑来，右舷的船首最先被浪冲到，缓缓爬升，将船首斜桅举向了空中；然后船身开始摇晃，慢慢的抬升着，船首斜桅的角度更高了；终于船身摇晃着越过了巨浪，船首腾在半空，伴随着大量的泡沫往下直坠；船首斜桅开始下指，船身则笨重的达到了短暂的平衡；接下来整个船身携着泡沫被大海推到风中，船尾被浪峰抬高；最后船头又回到水中。

Research purposes: To find out a simple and feasible computing method of skew frame to guide its design. Research methods:This paper analyzes the skew frame with 2D rigid frame and 3D space model of thick plate element with MIDAS Civil structure design system,and their results have been contrasted with comparison method.

随着交通运输事业的飞速发展，交通路网四通八达，铁路速度的提高及行车密度的加大，使用地少，投资小，施工方便的框架结构被大量采用，斜交框架结构日益增多，但是由于斜桥计算尚未形成完整的理论体系，这给铁路斜交框架立交桥的设计带来很大的困难。

Base on summarizing the development state of assembly skew hollow slab bridge, the research content of this dissertation has been determined. Taking Tuan Shan River Bridge, in Hubei province, China, as an example, the finite element method of space slab shell programmed in Ansys Parameter Design Language is adopted to analyze the elastic properties. By calculating the internal force influence surface of assembly skew hollow slab bridge, the internal force-controlling section is attained.
