摘要
以绥芬河斜拉桥转体施工为例,对斜拉桥施工监控中的设计参数敏感性进行了分析。选择主梁自重、混凝土弹性模量、斜拉索张拉力和刚度、混凝土收缩徐变及温度变化等设计参数,采用桥梁有限元分析软件——桥梁博士计算软件对各参数下的结构响应进行了敏感性分析,提出了影响大跨度预应力混凝土斜拉桥施工监控的主要参数。
An experiment was conducted to analyse the sensitivity of some design parameters in construction monitoring of cable- stayed bridge taking Suifenhe rotational cable-stayed bridge as an example. Some design parameters, dead weight of beam, modulus of elasticity of concrete, cable force and stiffness of cable-stayed bridge, shrinkage and creep of concrete, linear expansion coefficient of cable, and difference in temperature, were selected for sensitive analysis using finite element analysis software for bridges ( Dr. Bridge computation software). The principal parameters influencing the construction monitoring of cable-stayed bridge is presented.
