Problems solved by technology

[0003] When the railway track is set on the bridge, due to the influence of wind, temperature, sunshine and other natural environments, the bridge will undergo periodic deformation. There will be false periodic signals in the observation data, so the periodic deformation amplitude of the bridge calculated by GNSS technology is not accurate

Embodiment Construction

[0056] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0057] High-speed railway is an important infrastructure for the long-term economic and social development of the country. Long-span bridges for high-speed railways not only solve the needs of high-speed railways across large rivers, rivers and deep valleys, but also provide stable and smooth lines for trains, which is the key to ensuring good technical, economic and social benefits for high-speed railway projects.

[0058] The large cable-stayed bridge is a new type of bridge developed in modern times. The structure of this bridge is characterized by large spans, high towers, and flexible cable-stayed sections. Under the action of wind force, temperature change, sunshine, braking, concrete creep and other factors, the girder body will produce various deformations, which will affect the smoothness of the line on the bridge. The dynamic effect of high...

Abstract

The invention discloses a method, a device, electronic equipment and a storage medium for determining the amplitude of a bridge deformation period. Wherein, the method includes: according to the deformation sequence of each direction in the three directions of the bridge monitoring station, determine the deformation cycle corresponding to the periodic deformation of each direction of the bridge monitoring station; according to the deformation sequence of each direction and the corresponding deformation cycle, determine The error sequence in the deformation sequence in three directions; the error sequence in the three directions is combined, and according to the combined error sequence, the colored noise corresponding to the three directions is obtained respectively; based on the colored noise in each direction and the corresponding deformation sequence, Determining the deformation sequence after removing colored noise in each direction; and determining the amplitude corresponding to the periodic deformation in each direction of the monitoring station according to the deformation sequence after removing colored noise and the corresponding deformation period.

Description

technical field [0001] The invention relates to the technical field of deformation monitoring, in particular to a method, device, electronic equipment and storage medium for determining the amplitude of a bridge deformation cycle. Background technique [0002] As an important national infrastructure, national economic artery and popular means of transportation, high-speed railway has played a vital role in my country's economic construction, strengthening regional connections and enhancing the competitiveness of regional economic development. Therefore, to ensure the safe operation of high-speed railway very important. During the daily operation of the high-speed railway, the global navigation satellite system (GNSS) is often used to monitor the deformation of the bridge of the high-speed railway to ensure the safety of the railway. [0003] When the railway track is set on the bridge, due to the influence of wind, temperature, sunshine and other natural environments, the br...
