摘要
分析了温度对悬索桥锚跨索股张力的影响,通过数值解析法和有限单元法计算锚跨在空缆状态时对应的不同温度下的理论索力,并结合鱼嘴长江特大桥架设过程中的索力测试结果,提出一种锚跨索股张力的分析方法,并且介绍了索力检测设备及检测过程。
What this article studies is the influence research of temperature on suspension bridge anchor span strand tension, with the aid of the numerical-analytical method and finite element method, under spatial cable condition. The author calculates theory tension under different temperature, considers the test results of strand tension in the erection of yuzui Yangtze River Bridge and proposes the analysis method of anchor span strand tension. Cable testing equipment and testing process is also introduced.
