Zusammenfassung:	The invention provides a method for detecting the vibration speed and the vibration amplitude of a bridge. The method comprises the following steps: installing an acceleration sensor on a bridge to be detected, collecting acceleration values and displacement values in three directions through the acceleration sensor, and identifying that the bridge is in a static state according to the acceleration values and the displacement values; acceleration values of a bridge in three directions in a static state are collected in real time through an acceleration sensor, the vibration speed of the bridge is calculated according to the collected acceleration values, and the vibration amplitude of the bridge is calculated according to the vibration speed of the bridge. The invention provides the method capable of correcting the value of the acceleration sensor for detecting the bridge vibration, and the influence of the noise value and deviation of the acceleration sensor on the measurement of the bridge vibration charact
