重庆市东水门长江大桥、千厮门嘉陵江大桥合称“两江大桥”,其斜拉索采用超大吨位平行钢绞线斜拉索体系,稀索布置,索体规格为WQJX15.2-139,控制索力14500 kN。针对2座大桥施工现场实际情况以及所采用的钢绞线斜拉索体系的结构特点,对超大吨位钢绞线斜拉索的整体顶升张拉技术与应用进行介绍,说明超大吨位钢绞线斜拉索整体顶升张拉技术的可行性与优越性。
重慶市東水門長江大橋、韆廝門嘉陵江大橋閤稱“兩江大橋”,其斜拉索採用超大噸位平行鋼絞線斜拉索體繫,稀索佈置,索體規格為WQJX15.2-139,控製索力14500 kN。針對2座大橋施工現場實際情況以及所採用的鋼絞線斜拉索體繫的結構特點,對超大噸位鋼絞線斜拉索的整體頂升張拉技術與應用進行介紹,說明超大噸位鋼絞線斜拉索整體頂升張拉技術的可行性與優越性。
중경시동수문장강대교、천시문가릉강대교합칭“량강대교”,기사랍색채용초대둔위평행강교선사랍색체계,희색포치,색체규격위WQJX15.2-139,공제색력14500 kN。침대2좌대교시공현장실제정황이급소채용적강교선사랍색체계적결구특점,대초대둔위강교선사랍색적정체정승장랍기술여응용진행개소,설명초대둔위강교선사랍색정체정승장랍기술적가행성여우월성。
Chongqing Dongshuimen Yangtze River Bridge and Qiansimen Jialing River Bridge are collectively called “Liangjiang Bridge”, which stayed-cables adopt super tonnage parallel steel strand stayed-cable system with sparse arrangement of cables in size of WQJX15. 2-139 , and control cable force is 14500 kN. In allusion to actual conditions of construction site of two bridges and structural features of steel strand stay-cable system, this paper introduces tensioning technology for integral lifting of super tonnage steel strand stayed-cables and its application to demonstrate feasibility and advantage of tensioning technology for integral lifting of super tonnage steel strand stayed-cables.
