摘要
文章针对桥梁健康监测信息的时间序列具有季节、循环等非平稳状态的特点,提出了消除时间序列趋势项和平滑处理的信息处理方法,并结合重庆马桑溪长江大桥的工程应用实例,验证了该方法能够有效地剔除混杂在信号中的噪声干扰,减少测量数据的误差,为进行桥梁安全评估提供可靠的数据。
Because of the time sequence is seasonal and cyclical,the article gives the data interpretation method that smooths the gap.Combines with the real construction taken place at at Chongqing Masangxi Bridge,the article proves that these data analyzing method can effectively reduce the noises in the data and therefore improve he accuracy.
