At present, the general finite element calculation software of large bridges such as Midascivil and bridge doctor is mainly used for calculating and analyzing various bridge structures, but the bridge construction process cannot be directly controlled through the finite element software, complex analysis, processing and correction of calculation data need to be carried out by combining the actual conditions of the bridge construction site, in the analysis and processing process, the accuracy of monitoring and calculating results cannot be completely guaranteed due to a large number of manual processing steps, the calculating results are only limited to text tables with nonstandard and unified content forms, the visualization operation cannot be carried out, and the early warning function of a system does not exist.
bridge construction control (also called bridge construction monitoring) is very important for ensuring the safety of the bridge construction process and ensuring that the line shape and the internal force of a formed bridge meet the design requirements, and in the development history of bridge engineering, many bridges have bridge accidents caused by overlarge stress or stability problems in the construction process. The cantilever casting method is a construction method commonly used for bridge structures, particularly large-span bridge structures, the internal force and displacement of the bridge are constantly changed along with the progress of the construction process when the bridge is constructed by adopting the cantilever method, and the construction monitoring of the bridge is indispensable for ensuring the stress safety of the bridge structure in construction and achieving ideal line shape and internal force after the bridge is formed. The bridge construction monitoring mainly comprises geometric (linear) monitoring and stress monitoring, and specifically comprises bridge section displacement monitoring, stress monitoring, stay cable force monitoring, pier tower axis deviation monitoring, pier tower stress monitoring and the like.

The main process of bridge construction monitoring calculation comprises the following steps: step 1, full-bridge finite element simulation calculation; step 2, analyzing and processing finite element calculation data; step 3, establishing a data table of displacement and stress of the main beam segments in the whole construction process; step 4, comparing and correcting the theory of the suspended casting section of the main beam and the actually measured displacement value in the construction stage, and calculating the elastic deformation of the section of the main beam caused by the hanging basket; step 5, comparing and correcting the cantilever casting section theory of the girder and the actually measured stress value in the construction stage; step 6, calculating the elevation of the vertical formwork of the bottom plate of the beam section to be cast in a suspension mode; and 7, compiling a beam section construction monitoring instruction and a construction suggestion control measure.
in the prior art, step 1 is usually completed by large bridge general software Midascivil or bridge doctors, the technology is mature, for steps 2 ~ 7, technicians usually complete the data processing and compiling by office software excel, word and the like, however, the method mainly completes the data processing and compiling by manpower, the data processing and analyzing are complicated, the time consumption is long, errors are prone to occur, the accuracy and the precision of the data processing cannot be sufficiently guaranteed, the calculation result is limited to a text table, the normalization and the uniformity of the text table are poor, the method cannot perform visual operation, does not have a real ~ time early warning function, is not convenient for all parties such as construction, construction and supervision to control the stress deformation condition of the bridge structure in the construction process in real time, and accordingly has potential risks in the construction process, the data processing and compiling process in the traditional method does not have universality, the monitoring calculation and necessary actual measurement theory correction steps cannot be performed under a set of unified and standardized flow, and is not convenient for standardized construction management of enterprises to form a unified bridge monitoring and construction file.
