Zusammenfassung:The invention belongs to the field of bridge structure health monitoring, and discloses a cable-stayed bridge vehicle-induced cable force real-time online extraction method based on cable force monitoring data, which comprises the following steps: establishing a kernel density estimation model of operation cable force distribution; static load cable force extraction based on operation cable force distribution characteristics; performing real-time online updating on static load cable force based on moving window analysis; and establishing a time domain smooth model of static load cable force response to further extract vehicle-induced cable force. According to the method, accurate fitting can be realized when the prior information of the cable force distribution is unknown by establishing the kernel density estimation model of the operation cable force distribution, and the static load cable force is extracted based on the distribution characteristics; the moving window analysis model can effectively ensure en
