Presenting the calculating method of the space displacement model of skewed box girder, whit main ideas of: dispersing the skewed box girder into some skewed beam segments and further dividing those segments into some plate pieces according to their forms; describing the displacement functions in the plane of plate piece by assuming that the space displacements of any point in the joint line between the plate pieces are described by using Hermite interpolation functions and that two displacements in the plane of plate piece are linear in the cross direction; Using Hermite interpolation functions to describe the bending the displacement of the unit length transverse frame cutting longitudinal from the skew box girder segment; Finally, describing the space displacements of a point in the plate pieces by two displacements in the plane of the plate and one bending displacement of plate.

提出了斜交箱形梁空间位移场的计算方法：将斜交箱形梁沿纵向离散为若干斜梁段单元，依据箱梁的构成进一步将斜梁段划分为若干板段子单元；各板段联结线上任意点的位移按Hermite函数插值，假定各板段的面内位移沿其宽度方向线性变化，以描述各板段面内位移；沿斜交箱梁段的纵向截取单位长度横截面框架，框架各杆件空间位移按Hermite函数插值，以描述各板段面外位移；板段内任意点的空间位移最终以2个面内位移和1个面外位移描述。

The entire Superstructure cross-section, except for traffic barrier, shall be considered to be placed at one time for purposes of determining support requirements and designing falsework girders for their stresses and deflections, except as follows: For concrete box girder bridges, the girder stems, diaphrams, crossbeams, and connected bottom slabs, if the stem wall is placed more than 5 days prior to the top slab, may be considered to be self supporting between falsework bents at the time the top slab is placed, provided that the distance between falsework bents does not exceed 4 times the depth of the portion of the girder placed in the preceding concrete placements.

整个上部结构截面除交通障碍，应被视为在一个确定的要求和支持他们的设计应力和挠度除，脚手架时间放在梁的目的如下：对于混凝土箱形梁桥，主梁茎，diaphrams，横梁，和连接底板，如果干墙放置超过5天前向顶板，可能被认为是自我支持之间的脚手架本茨当时顶端板放置，只要脚手架茨之间的距离不超过4倍，在前面的混凝土主梁部分存款放在深度。

两头的钢箱梁利用大吨位吊车和已经就位好的钢箱梁对接架设。很好地解决了单片整体吊装钢箱梁接头变形影响问题。

Through contrast analysis of stress value,the paper found warren box girder can improve prestress and precompression of prestress concrete box girder under border and box girder bearing capacity,reduce the distribution of prestress wire,saving construction quantity.

通过对同等条件的直腹箱梁和斜腹箱梁的应力值对比分析，提出将直腹箱梁改为斜腹箱梁后，可以提高预应力混凝土箱梁下缘的预压应力，提高箱梁承载力，降低预应力钢绞线的配置，节省工程数量。

The section deformation of the box girder is obviously different between the girder segment to be hoisted and the cantilever system supporting the walking crane during the cantilever erecting due to different applied loads.3D finite element models for girder segments are developed.

在悬臂拼装过程中，由于作用的荷载不同，被吊梁段与吊机作用梁段的变形明显不同。

介绍铁路栈桥利用浮吊吊装钢梁安装技术、梁梁连接过渡配合轴孔穿轴技术以及高精度支座安装技术。

Taking into consideration of the case that the rigidity of spatial latticed girder construction was higher than that of suspended cable construction, it was proposed that the latticed girder was used to construct a suspension bridge with truss stiffened by plate-latticed girder instead of the conventional stiffening truss.

利用空间网架结构刚度大而悬索结构刚度较低的特点，提出采用网架结构代替常规悬索桥的加劲梁，构成平板网架－悬索桥。

The ZTP II series rubber support is suitable for T girder. it uses the column kneading board and the roof coordination, to make it only carry on longitudinally automatic stepless moved slope, which may avoid the question of the girder list effectively, moreover, ZTP series rubber support because its can adapt the random orientation slope, the bottom of the girder the embedded steel plate does not allow to design the wedge shaped block, therefore specially

ZTPⅡ系列橡胶支座更适用于T型梁，它采用柱面板和顶板的配合，使其只能进行纵向的自动无级调坡，可以有效地避免架梁时的侧倾问题，另外，ZTP系列橡胶支座由于其能适应任意方向的坡度，梁底预埋钢板不许设计楔形块，因此特别适宜于在顶推连续梁上采用。
