摘要
为研究多塔斜拉桥大吨位斜拉索安装中的相关问题,依托某实际桥梁工程,阐述该桥梁大吨位斜拉索安装施工工艺,然后对锚具安装、斜拉索挂索、张拉和调索等施工要点进行研究。结果表明该大吨位斜拉索结构承载能力完全满足要求,安装过程中应严格遵守施工要求,保证拉索和工具完好。
Based on the actual reinforcement project of a bridge,the construction technology of large tonnage stay cable installation of the bridge is illustrated.The construction points such as anchorage installation,stay cable hanging,tensioning,and cable adjustment are studied.The results show that the bearing capacity of the large tonnage cable structure fully meets the requirements that should be strictly followed during installation,in which the cables and tools are in good condition.
