Abstract
本申请涉及桥梁结构健康预警技术领域，公开了一种桥梁动态响应监测与预警方法，该方法包括：识别单辆重载车辆并提取其物理空间几何数据；基于物理空间几何数据对不同观测截面采集的原始动态响应时间序列进行相位对齐处理，得到动态响应时间序列；再基于动态响应时间序列计算相邻观测截面间的动态应变传递函数并生成纵向空间传递状态向量；将所述纵向空间传递状态向量与健康基准进行概率距离测度，并基于测度结果判定是否输出触发指令。本发明利用物理空间几何数据对响应信号进行自洽性验证和规整约束，并结合概率距离测度进行状态评估，解决激振源不确定与车辆变速导致的监测数据失真问题，提升了预警决策的准确性与鲁棒性。
