箱形梁

Comparing the results of one irregular box beam obtained by the gridiron method to that by FEM, the characteristics of the application scope, merits and drawbacks of the gridiron method are convinced.

对上德立交桥中的一联异形箱梁通过不同的方法以及试验进行分析和计算，详细地说明了异形箱梁设计中常常使用的梁格法的适用情况和实际的效果。

The Jiayue Bridge in Chongqing is an extradosed bridge with double Y-shape pylons,double cable planes and with a main span 250 m.

重庆嘉悦大桥是一座双塔双索面Y形矮塔斜拉桥，桥梁主跨跨径250m，主桥箱梁采用单箱单室大悬臂结构形式，介绍大桥总体设计思路。

In this dissertation, considering the influence of transverse shearing deflection and noncoincidence of torsion center and gravity center, the equilibrium formulas of variable-curvature box-girder with rectangular cross section were established. Based on deformation expression of arbitrary point on the girder and relationship between inner forces and displacement equations, considering noncoincidence of torsional center and gravity center, the governing differential equations for variable-curvature box-girders were generalized.

针对具有竖直对称轴的矩形断面变曲率箱梁，考虑了挠曲剪切应变和曲梁剪心和形心分离的影响，推导了变曲率箱梁的平衡方程；通过箱梁内任一点的位移方程和内力-位移关系，推导了考虑曲梁剪心和形心分离的变曲率箱梁的挠曲扭转控制微分方程。

Shuangzhu mechanical vehicle lift, which includes two box-shaped Jusheng pillar, two vertical sliding in the box-shaped piece of Jusheng-piece aircraft, two up and two track-holding arm, their identity is in Jusheng pillar box-shaped structure in part by the end of Liang-bed or carpenter's square or rectangle gear boxes and gear boxes on both sides of a square-short margin upward extension of the upper beam connecting a pillar overall; Jusheng pillar box is described below rectangle gear boxes installed electric motors is one of the driving boxes; and the piece-by-two parallel fixed in its orbit above the occasional arm-supporting, through the Hua Tao Kong spaces interlinked.
