摘要:
提出基于自适应重要抽样的可靠度分析方法,并给出具体实现步骤; 以角笼坝大桥、海沧大桥、坝陵河大桥、西堠门大桥4座不同跨度的悬索桥为背景,根据理论计算与实际的试验数据得到了悬索桥跨度、高差、垂度、钢丝直径、弹性模量、温度的分布情况,然后用该方法对它们的基准索股可靠度与空缆线形可靠度进行分析计算,并讨论了参数的敏感性。结果表明:在现有的测量精度下,随着跨度的增大,基准索股施工线形达到设计线形的可靠度指标减小; 随着主缆索股根数的增加,空缆线形可靠度指标减小; 对于基准索股线形,弹性模量是最主要的影响因素; 对于空缆线形,温度是最主要的影响因素。
Abstract:
The reliability analysis method on the basis of adaptive importance sampling was proposed and the concrete steps of this method were presented. Four suspension bridges including Jiaolongba Bridge, Haicang Bridge, Balinghe Bridge and Xihoumen Bridge, which differed from each other in span, were taken as examples. According to theoretical calculations and actual experimental data, the distributions of span, height difference, sag, steel wire-diameter, elastic modulus and temperature were obtained. Then the mentioned analysis method was used to calculate and analyze the reliability of datum strand and unloaded cable shape, as well as to discuss the parametric sensitivity. The study result shows that, under the current measurement accuracy, the reliability index of construction geometry of datum strand meeting the design geometry decreases as span increases; the reliability index of unloaded cable shape decreases as main cable strand increases. For the datum strand shape, elastic modulus is the most important factor while temperature has the greatest influence on the unloaded cable shape.
