Beschreibung
Zusammenfassung:	The invention discloses a device and a method for testing gradient and oscillation of a cable-stayed bridge tower. The device comprises a cable tower oscillation test laser emission device I, a cable tower oscillation test laser emission device II, a cable tower oscillation target spot device I and a cable power oscillation target spot device II. The device is characterized in that the cable tower oscillation test laser emission device I and the cable tower oscillation test laser emission device II are respectively arranged at the upstream side and the downstream side of a cable-stayed bridge bearing platform. The cable tower oscillation target spot device I and the cable power oscillation target spot device II are respectively arranged on the side surface of the upstream of the top and the side surface of the downstream of the middle of a cable-stayed bridge cable tower. The device has the characteristics of large measuring range, high precision, good resolution, reliability in working, convenience in operat
