摘要

提出了基于交叉验证的新颖性检测方法，对环境因素影响下的中小桥梁群损伤进行检测。通过一个由五座相似桥梁组成的桥群的数值算例，验证了该方法的有效性。同时，通过与传统新颖性检测方法的有效性比较，讨论了该方法的优缺点。数值结果表明，基于交叉验证的桥群新颖性检测方法能有效减轻环境因素对损伤检测的影响。

Cross validation-based novelty detection of bridge group

Novelty detection based on cross validation was proposed to detect the damage of the cluster of medium and minor bridges under the effect of environmental factors. The effectiveness of this method was tested through the numerical example of one bridge group that was composed of five similar bridges. Meanwhile, advantages and disadvantages of this method were discussed by comparing the effectiveness between proposed method and traditional novelty detection method. The numerical results showed that the cross validation-based novelty detection of bridge group method effectively mitigated the influence of environmental factors on damage detection.
