【摘要】 本文通过对斜拉桥索力监测技术研究成果及工程经验进行回顾和总结，研究了目前常用的索力量测方法(即振动频率量测法)的使用范围及带减振器拉索索力量测的缺陷，分析了带橡胶组合减振器拉索的构造特点及力学特性，建立了带橡胶组合减振器拉索的动力学模型，根据能量原理，推导出了考虑减振器影响的索力计算公式，并在青岛丹山斜拉桥进行了应用，取得了预期的效果，为同类桥梁的施工控制与运营管理，特别是为带橡胶组合减振器拉索索力监测提供了理论依据与技术保障。更多还原

【Abstract】 Through reviewing and summarizing to the existing study achievements and project experiences, this paper studies the common method used to measure cable force (method of measuring vibration frequency), points out its adaptive limits and the shortage in measuring the force in cables with shock absorber. The paper also analyzes the structural characters and mechanics properties of cable with shock absorber and sets up the dynamics model. According to the energy principle, this paper carries out the calculation method considering with the effect of shock absorber, applies it to DanShan cable-stayed bridge in QingDao, and obtains the expected result, which provides theoretic basis and technological preservation to the construction control and operation management of same type bridge especially to force monitoring in the cables with shock absorber.更多还原
