Abstract

The invention discloses a bridge mechanics real-time analysis method based on finite variables. The method is based on the design of a bridge. Variable parameters influencing the stress of the bridgeare variables such as an invariable load, an automobile load, forced displacement, a temperature gradient and the like; characteristics of various variables are studied; data tables are designed for different variables respectively to form a database; under vehicle load variables, an influence surface of a bridge is established, a numerical value of the influence surface is stored in a table, whena vehicle load changes, a bridge effect under the action of a load is analyzed through the influence surface under the action of a unit load, effect values are analyzed under different current loadsone by one, and finally calculating is carried out to obtain a mechanical effect of the bridge through an effect superposition principle. The mechanical effect of the bridge can be analyzed in real time, and the situation that the real-time effect of the bridge cannot be obtained in time in the construction and maintenance stages and the safety of the bridge structure cannot be evaluated is avoided.

Description

technical field

[0001] The invention belongs to the field of bridge structure analysis, in particular to a real-time analysis method of bridge mechanics based on finite variables. Background technique

[0002] At present, the mechanical analysis of bridges is only calculated for specific scenarios, such as the safety of temporary auxiliary structures during the construction period, and the special load check calculation during the operation period. For daily bridge conditions, calculations are generally not performed, but in the daily bridge maintenance process. In the middle, especially the bridge, it is necessary to quickly analyze its structural safety, compare and monitor the difference and change trend between the actual data and the theoretical data calculated by the numerical calculation in time, so as to quickly grasp the mechanical status of the bridge and serve the construction and maintenance stages.

[0003] The technical problems existing in the prior art are: ...
