摘要
山区铁路地形变化高差大,铁路设计时桥隧众多,而且桥梁高墩大跨占了很大的比例,其高墩施工环境复杂、安全风险高,对山区铁路桥梁建设提出了更高的要求。本文以某山区铁路特大桥空心薄壁墩墩身施工为例,对空心薄壁高墩封顶施工技术进行探讨研究。
The altitude of Mountain Railways are always with lots of change and there are numrous bridges and tunnels.And bridges with high-pier and long-span account for a large proportion.The high-pier construction environment is complex and with high safety risk.So the Mountain Railway bridge construction proposed higher requirements.Here is a example in this passage about a Mountain Railway super large bridge hollow thin-walled high pier construction and a research of its construction technology of the cap.
