Highway bridge management and maintenance PHM system and method based on BIM

Abstract

The invention provides a BIM-based highway bridge management and maintenance PHM system and a BIM-based highway bridge management and maintenance PHM method, which are characterized in that information of each stage of a bridge is integrated based on a BIM technology, and visualization, standardization and informatization of bridge data are realized; the comprehensive monitoring and inspection of the bridge and the environment are realized; bridge diseases are diagnosed and predicted based on the highway bridge disease library, and the function of guiding long-term maintenance of highway bridges is achieved. According to the invention, information classified storage, comprehensive analysis and disease diagnosis and early warning functions are realized, design, construction, operation and maintenance information is associated and stored, and big data processing is carried out on comprehensive monitoring and inspection information of roads, bridges and environments, so that diagnosis and prediction of bridge diseases and evaluation of health conditions are realized; and a decision basis is provided for highway bridge maintenance. The method is a multi-angle, multi-parameter and multi-source data big data analysis method integrating health monitoring and manual inspection, has the advantages of being visual, accurate and efficient, and meets the requirements of highway bridge management.

Description

technical field [0001] The invention belongs to the technical field of road bridge management and maintenance, and in particular relates to a BIM-based PHM system and method for road bridge management and maintenance. Background technique [0002] At present, the service time of bridges in our country is generally short, and the safety situation is generally good, but its prospects are not optimistic. Bridges are affected by factors such as environmental changes, natural disasters, and gradually increasing traffic loads, resulting in bridge deterioration, abnormal component deformation, and reduced bearing capacity, which are directly related to the smooth operation and safety of highways. In the process of highway and bridge construction and maintenance, we are faced with the problem of disconnected management caused by different companies responsible for design, construction and management and maintenance. As a result, the highway and bridge management department can only ...

Problems solved by technology

Compared with long-span railway bridges, the maintenance of a large number of small and medium-span bridges on ordinary roads has not received enough attention, resulting in the general problem of reduced durability of existing road bridges, which highlights the importance of road bridge management and maintenance based on PHM technology. method importance
