空间索面斜拉桥拉索安装及张拉影响分析
摘要
Abstract
Cable installation and cable force adjustment are the key to control during the construction process of cable-stayed bridges.Taking the Xuefu Road cable-stayed bridge in Shijiazhuang City as an example,this paper introduces the cable hanging technology and tensioning control method.Based on the actual measurement and simulation analysis results,the influence relationship between the cable installation and tensioning process on the main tower deflection,stress and the stress state of the main beam is analyzed,and the mechanical behavior characteristics of the bridge structure during the cable tensioning process are obtained.The measured cable force value of the cable after secondary cable adjustment is given.It shows that the maximum error between the measured cable force and the design cable force is not more than 7%,which meets the specifications and design requirements.It also proves that the cable construction and cable adjustment control methods in this paper are reasonable and provide technical guarantee for the bridge to achieve ideal alignment and stress state.关键词
