不同支撑条件下钢-混叠合梁内应力的计算与分析

Internal Stress Calculation And Analysis of Steel - Concrete Composite Beam under Different Support Conditions

钢结构箱梁具有强度高、自重轻、跨度大、施工速度快及抗震性能好等优点,广泛应用于城市、铁路大跨度桥梁的施工中。以乌鲁木齐市克拉玛依路高架桥钢箱梁施工实践为例,主要介绍大跨度钢箱梁施工过程中临时支撑的设置对钢箱梁内力控制的影响,仅供同类项目施工参考。

Steel box girder has the advantages of high strength, light weight, large span, the construction speed, good seismic performance, widely used in the city, railway construction of long-span bridges. In this paper, Urumqi, Karamay Viaduct steel box girder construction practice, for example, introduces the internal force control of the steel box girder span steel box girder construction process to set up a temporary support for the construction of similar projects reference.
