Abstract

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 operation and the like, is capable of carrying out continuous testing in an all-weather manner and outputting test data in real time, and provides novel instrument and equipment for testing the gradient and the oscillation of the cable-stayed bridge tower.

Description

technical field [0001] The invention relates to an instrument and method for testing the inclination and swing of a cable-stayed bridge tower, in particular to a tester for the inclination and swing of a cable-stayed bridge tower and a testing method thereof. Background technique [0002] At present, theodolites are often used to test the inclination of cable-stayed bridge towers, and vibration pick-up instruments are used to measure the swing of cable-stayed bridge towers. The inclination and swing of the bridge tower, and the inability to continuously output monitoring signals in real time. Contents of the invention [0003] Aiming at the deficiencies of existing instruments and equipment for testing the inclination and swing of cable-stayed bridge towers, the present invention proposes a tester for the inclination and swing of cable-stayed bridge towers and a testing method thereof, which can continuously and uninterruptedly monitor all-weather, Real-time output of dat...
