摘要
以崖门大桥主梁施工过程作为工程背景,采用作者提出的杆系随机域外奇点法对施工中的崖门大桥进行了静力随机分析,考察了不同材料参数与荷载参数的变异对主梁挠度、塔顶位移与斜拉索索力的影响程度,从而为大桥主梁施工监控过程中的参数识别与施工调整提供了依据。
The stochastic analysis of static force for Yamen Bridge at erection stage is performed by the stochastic singularpointsoutsidedomain method proposed by the authors. The effects of variation of different material and loading parameters on the deflection of the bridge girder, the displacements at the tops of pylons and the cable forces are considered in the analysis, which provides the bases for parameter identification and erection adjustments during construction control of the bridge girder.
