| 摘 要： | 建造弯斜桥，不但能使整个线路线形美观流畅，而且可以缩短桥长，节省建设用地、投资和材料，提高经济效益，因此斜弯梁结构已广泛应用到城市道路、立交枢纽和高等级公路中。以绍兴某智慧快速路工程为例，通过对主跨箱型叠合梁在施工过程中的工作性能研究，提出槽型开口钢箱在架设过程中的防扭措施。

| Abstract: | The construction of curved skew bridges can not only make the alignment of the whole line beautiful and smooth, but also shorten the bridge length, save the construction land, investment and materials, and improve the economic efficiency. Therefore, the skew curved beam structure has been widely used in urban roads, interchange hubs and high-grade highways. Taking a smart expressway project in Shaoxing as an example, through the research on the working performance of the main-span box-type composite beam in the construction process, the anti-torque measures for the slotted open steel box in the erection process are proposed. |
