Bridge construction whole-process control and visual early warning system

Abstract

The invention discloses a bridge construction whole process control and visual early warning system. By collecting calculation data of finite element software, the system can be applied to whole-process construction monitoring of various bridge structures adopting a cantilever construction method, including bridge structure construction monitoring in the aspects of bridge segment displacement, stress, stay cable force, pier tower axis deviation, pier tower stress and the like. The system can automatically measure, acquire and organize displacement and stress actual measurement results of various bridge segments. By access to finite element calculation software such as Midasecivil and bridge doctors, key information data of the bridge structure is acquired. Acquired actually-measured and theoretically-calculated data are analyzed through a built-in data processing and analyzing function. On one hand, a data result obtained through analysis can be broadcasted in real time and stress anddisplacement early warning information can be published through the visualization and early warning module, and on the other hand, a beam section formwork erection elevation instruction table and various construction monitoring text files can be output in a customized and unified mode through the standardized output module.

Description

Technical field [0001] The invention relates to the related field of bridge construction control, in particular to a whole process control and visual early warning system of bridge construction. Background technique [0002] The cantilever pouring method is a commonly used construction method for bridge structures, especially long-span bridge structures. In the cantilever pouring method, how to determine the elevation of the bottom plate of each beam section of the bridge, analyze and control the displacement and stress of the bridge beam section to make the bridge construction line shape and stress The key to force control. At present, the general finite element calculation software for large bridges such as Midascivil and Bridge Doctor is mainly used for calculation and analysis of various bridge structures. However, the finite element software cannot directly control the bridge construction process. The calculation data needs to be combined with the actual situation of the bri...

Problems solved by technology

[0006] In the prior art, step 1 is usually completed by the large-scale bridge general software Midascivil or Dr. Bridge, and the technology is relatively mature; and for steps 2~7, technicians usually use office software excel, word, etc. to complete, but this method carries out data analysis. Processing and writing are mainly done manually. Due to the complexity of data processing and analysis, it takes a long time and is error-prone, and the correctness and accuracy of data processing cannot be fully guaranteed; the calculation results are limited to text tables, and the standardization of text tables , poor uniformity; no visual operation, and no systematic real-time early warning function, it is not convenient for construction, construction, supervision and other parties to control the stress and deformation of the bridge structure in real time during the construction process, resulting in bridges in the construction process. Potential risks; the process of data processing and writing in traditional methods is not universal, and the monitoring calculation and necessary measurement-theoretical correction steps cannot be carried out under a set of unified and standardized procedures, which is not convenient for department / enterprise standardized construction management, and is not conducive to Form a complete and unified normative bridge construction monitoring document
