| 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。

| Abstract: | 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. |
