斜腿刚构在跨线桥施工中的应用分析

Application Analysis of Inclined-leg Rigid Frame in Construction of Overpass Bridge

斜腿刚构具有材料成本低、跨径使用程度高以及造型美观等特点,在很多跨线桥工程中得到大量应用,而其实际应用过程中也存在一定的质量问题,因此需加强对斜腿刚构在跨线桥施工中的应用研究。文章阐述了斜腿刚构在跨线桥施工应用中的优缺点,并结合工程案例对跨线桥斜腿刚构施工工序的质量控制要点进行分析,以期为保证斜腿刚构在跨线桥施工过程中的应用质量提供借鉴。

The inclined-leg rigid frame has many characteristics such as low material cost, high span utilization degree and aesthetic appearance, which has been widely used in many overpass bridges, but its practical application has some quality problems, thus the application study of inclined-leg rigid frame in the construction of overpass bridges needs to be strengthened.This article described the merits and demerits of inclined-leg rigid frame in the construction of overpass bridges, and combined with engineering examples, it analyzed the key quality control points for the construction process of inclined-leg rigid frame of overpass bridges,thereby providing the reference for ensuring the application quality of inclined-leg rigid frame during the construction of overpass bridges.
