摘要
新建湘桂铁路于DK233+503处下穿全兴高速公路,原设计采用顶进框架桥方案。通过对安全质量的可控性、经济、工期等方面进行综合比选,取消顶进框架桥,变更为公路箱梁桥上跨铁路方案,采用分幅封道、分幅施工,既安全快速地穿过全兴高速公路,又创造了良好的经济效益和社会效益,为类似的工程提供了一定的参考价值。
The original design of the project of DK233 ＋ 503 section of newly built Xianggui Railway beneath Quanxing Expressway used jacking frame bridge scheme. Through the comprehensive comparison of the controllabilityof safety and quality, economy, duration and other aspects, jacking framebridge scheme is cancelled, and the highway girder bridge across railway scheme is proposed. The railway safely and quickly crossed the Quanxing Expressway by using framing closed traffic and framing construction, which created good economicand social benefits and provided a certain reference value for the similar project.
