| 摘 要： | 结构在施工期的平均风险远远高于使用期,开展大跨度斜拉桥施工期间的风险分析研究是十分必要的。本文在介绍风险分析基本原理的基础上,针对斜拉桥施工期风险分析中不存在显式的极限状态函数的问题,提出了基于人工神经网络-有限元-蒙特卡罗模拟的风险分析方法。运用该方法对某大跨度斜拉桥进行施工风险分析,结果表明该方法可行、有效。

| Abstract: | The average risk of structure in construction period is far higher than one in use period.To make the risk analysis study is very necessary in the construction of large-span cable-stayed bridge.The paper puts forward the simulated risk analysis method on basis of man-made nervous network-finite element-Monte Carlo Method.To make the construction risk analysis of a large-span cable-stayed bridge by this method,the result shows that this method is feasible and effective. |

| Keywords: | cable-stayed bridge risk analysis nervous network construction period |
