The Meijing Bridge is a prestressed concrete long-span continuous bridge. Based on it,this paper build a FEM model to analyze the infulence of construction procedure on the pre-camber setting of this bridges.
指出美景大桥为大跨度预应力混凝土连续梁桥,以其为工程背景建立有限元模型,分析了悬臂施工中影响预拱度的各项因素,通过合理的计算和理论分析确定了桥梁施工过程中在受力和变形方面的工作状态,为类似桥梁工程的施工控制分析提供了参考。

N-COUNT A camber is a gradual downward slope from the centre of a road to each side of it. 拱形
Auxiliary surface is commonly used as a graphic solution for the projections of the intersection line of quadratic cambers of revolution.
在两个二次回转曲面体相贯线的求解中，辅助面法是常用的图解方法。
With the ordinary camber used as auxiliary cross section, the line of intersection of two biasing single cambers is worked out in a view with the method for line of nodes.
本文以一般位置平面为辅助截平面，用求迹线方法，在一个视图求作两单曲面偏交交线。
It took a great deal of structural analysis work on our part so that we would be able to tell the contractor to build the right cambers so they would all go to the zero baseline elevation.
在我们做大量的结构分析工作之后我们才能让承包商去建造正确的拱。这样他们全都会去做零高程基准工作了。
