Overall synchronous tensioning treatment method for cable-stayed bridge inhaul cable
The invention belongs to the technical field of cable-stayed bridge inhaul cable tensioning, and particularly relates to an overall synchronous tensioning treatment method for a cable-stayed bridge inhaul cable. The method provided by the invention comprises the specific steps of establishing a tension process reference value; debugging an on-site tensioning numerical control equipment system; carrying out stage splitting according to the optimal finished bridge cable force; setting allowable error ranges of force and displacement; and then, completing the bridge tensioning process in three stages, finally tensioning the finished bridge cable force in place, conducting observation for 24 hours, theoretically calculating and analyzing the deviation between a final field result and a predicted value, and if the deviation is within the allowable error range, ending the whole tensioning process, recording, copying and sorting to obtain a final tensioning report. According to the invention,the numerical control synchronization technology is expanded and applied to the field of cable-stayed bridge inhaul cable tensioning, the working efficiency is greatly improved, the precision of finished bridge inhaul cable force is improved, personal errors caused by manual control operation are eliminated, the stress performance of a main stress component in the tensioning process is improved,and thus the whole tensioning process is accurate, rapid and convenient.
本发明属于斜拉桥拉索张拉技术领域，具体为斜拉桥拉索整体同步张拉处理方法。本发明方法具体步骤包括：建立张拉过程基准值；调试现场张拉数控设备系统；根据最优成桥索力进行阶段拆分；设定力、位移的允许误差范围；然后分三个阶段，完成桥梁张拉过程，最终成桥索力张拉到位，持荷24小时进行观测，理论计算分析最终现场结果与预测值的偏差，在误差允许范围内，则整个张拉过程结束，记录、誊写梳理最终张拉报告。本发明将数控同步技术拓展应用到斜拉桥拉索张拉领域，大大提高了工作效率，提升成桥拉索索力的精度，消除了手工控制操作造成的人为误差，改善了张拉过程中主受力构件的受力性能，从而达到整个张拉过程的精准、快捷、方便。
