Civil engineering structure safety monitoring system

The invention relates to a civil engineering structure safety monitoring system, which comprises a transverse vibration table (1), a longitudinal vibration table (11), a comprehensive vibration table,data monitoring equipment (23) and a monitor (3). The transverse vibration table is provided with a first vibration motor (2); the longitudinal vibration table (11) is provided with a second vibration motor (8) and a third vibration motor (13); the first vibration motor (2) drives the comprehensive vibration table to move horizontally; the second vibration motor (8) and the third vibration motor(13) drive the comprehensive vibration table to move up and down; the data monitoring equipment (23) monitors data of a civil engineering structure (22) and sends the data to the monitor (3) for safety monitoring; and the monitor (3) adjusts driving signals of the first vibration motor (2), the second vibration motor (8) and the third vibration motor (13) according to the monitored data so as to conduct all-around safety m
