摘　　要：介绍了蒙特卡罗数值模拟的基本原理及方法。以润扬大桥状态评估系统为例 ,对大桥在正常运营和损伤状态下的结构可靠度进行分析 ,对超过限值的结果进行预警 ,其分析结果形象直观 ,提高了评估的效率 ,使维护决策的制定更加客观准确。In this paper,the condition assessment method using Monte Carlo Simulation is presented,combined with the condition assessment system on Runyang Bridge,the structural probability under normal and damaged situations are calculated.The results are visual and understandable,so the efficiency of assessment is increased and the decision-making of maintenance is more objective and accurate.
