轨道层部分预应力混凝土梁预应力度控制

The pre-stress effort control of track layer partially pre-stressed concrete beam

通过考虑站房结构承受动力荷载的特殊性,又兼顾框架结构的特点,对站房结构进行有限元结构离散分析,通过不同规范下预应力度的设计比较,以合理选择预应力度进行控制设计。

By considering the particularity of station structure under dynamic load, but also took into account the characteristics of frame struc- ture, this paper made finite element structure discrete analysis on station structure, thrOugh the design comparisons to pre-stressed effort under different specifications, so as to select reasonable pre-stressed effort to control design.
