一种新型的车站轨道梁站台梁一体结构

A new type of station rail beam and platform beam integrated structure

为提高车站轨道梁、站台梁的性能,克服现有轨道梁、站台梁的弊端,提出一种新型的轨道梁站台梁一体结构,在满足车站使用功能的前提下,对结构的外观和尺寸进行优化。该结构形式在横向上压缩了轨道梁和站台梁的总宽度,在竖向上降低了车站的轨面标高,能节省工程造价及运营维护费用;提高结构的抗震安全性能;避免楼扶梯外挂,有利于整个车站的景观设计及建筑布局。通过建立平面及空间有限元模型分析,结构在各种工况下的性能指标均满足要求。

In order to improve the performance of the station rail beam and platform beam,overcome the shortcomings of existing rail beam and platform beam,this paper presents a new rail beam and platform beam Integrated structure. In the premise of the station to meet the use function,the appearance and the size of the Integrated structure are optimized. The structure reduces the total width of the rail beam and the platform beam and the elevation of the rail surface of the station,saves engineering cost and operation and maintenance cost. It improves the performance of seismic safety of structure and avoids the staircase plug-in,benefit for landscape design and architectural layout for the whole station. Through the establishment of plane and space finite element model analysis,performance index of the Integrated structure under various working conditions are satisfied. Based on the calculation and analysis,this paper puts forward reasonable suggestions for the design and application of the structure.
