摘要
山区跨越深切峡谷斜拉桥钢混组合梁施工方案的选择不同于跨域大江大河及海上斜拉桥施工,因其受地形地貌限制问题较为突出.研究以某特大桥为背景,对比分析了采用缆索吊机整节段施工与悬臂拼装桥面吊机整节段施工钢混组合梁斜拉桥在各方面的优缺点,以期为以后施工类似工程提供一定借鉴作用.
Abstract
The selection of steel-concrete composite girder construction scheme of cable-stayed bridge across deep canyon in mountainous area is different from that of cable-stayed bridge across big river and sea,because it is limited by topography and landform.Based on the background of a large bridge,this paper compares and analyzes the advantages and disadvantages of the cable-concrete composite girder cable-stayed bridge constructed by cable crane and cantilever deck crane,in order to provide some reference for the construction of similar projects in the future.
