施工程序对边主梁截面斜拉桥中的横梁受力影响

以金马大桥为例，通过建立空间有限元模型，考虑不同的施工程序，对斜拉桥中边主梁截面的横梁进行受力分析表明，分批张拉预应力筋可以使同一块件的两根横梁的受力更加均匀，在恒截作用下，距离塔较远处的横梁受力与简支梁相同。

Effection of Construction Program to Transverse Beam in Cable-Stayed Bridge with Side Main Beam as Section Form

The transverse beam force in the cable stayed bridge with main beam as section form is analyzed through taking Gold Horse Bridge for example, establishing space finite element model and considering different construction programs. The analyses indicats that it can make the force of the transverse beams in a segment distributes more evenly. Under static load the force in transverse beam farther away from the pylon is similar to the simple supported beam.
