客货共线铁路T梁圆端形空心墩参考图总体设计

结合客货共线铁路简支T梁圆端形空心墩参考图的设计,对设计空心墩的总体性要素、构造尺寸的确定进行详细分析,总结空心墩设计时需计算的项目及计算的原则。采用合理设计方案和结构尺寸,可以获得桥墩合适的刚度,节省墩身和基础材料,简化施工,提高模板的利用率,达到降低工程造价的目的。

General Design of Round-ended Hollow Pier Reference Plot for Mixed Passenger and Freight Railway

Based on the reference plot design of simple-supported T-shaped girder round-ended hollow pier for mixed passenger and freight railway, this paper analyzes the general elements and the determination of structure size,and summarizes the items that should be calculated and calculation principles. The results show that appropriate stiffness can be acquired with proper design scheme and structure size to save materials for pier and foundation,simplify construction organization,improve formwork utilization and reduce project cost.
