Bridge safety monitoring and early warning system based on BIM

Abstract

The invention discloses a bridge safety monitoring and early warning system based on a BIM. The bridge safety monitoring and early warning system comprises an on-site sensing element, a BIM bridge three-dimensional simulation system, a Midas bridge finite element safety calculation system and a remote data acquisition system; the on-site sensing element is used for collecting stress-strain real-time data of a bridge on-site stress point; the remote data acquisition system is used for receiving stress-strain real-time data of a bridge on-site stress point acquired by the on-site sensing element; the Midas bridge finite element safety calculation system is used for analyzing the stress condition of the bridge; and the BIM bridge three-dimensional simulation system carries out critical touch on a Midas bridge finite element model. According to the invention, technical support can be provided for real-time performance and visualization of bridge safety monitoring and early warning; when unpredictable deformation and cracks happen to the bridge under the load condition, personnel can be maintained or evacuated in time, the damaged part is clear through visualization, detection is conducted through reduced manpower and material resources, and therefore the best opportunity of maintenance is prevented from being delayed.

Description

technical field [0001] The invention relates to the technical field of bridge safety monitoring, more specifically, it relates to a BIM-based bridge safety monitoring and early warning system. Background technique [0002] BIM (Building Information Modeling) technology was first proposed by Autodesk in 2002, and it has been widely recognized by the industry around the world. It can help realize the integration of building information, from building design, construction, operation to the whole life cycle of the building All kinds of information are always integrated in a 3D model information database. The design team, construction unit, facility operation department and owners can work together based on BIM to effectively improve work efficiency, save resources, reduce costs, and achieve sustainable development. [0003] The existing bridge safety monitoring and early warning system cannot provide technical support for the real-time and visualization of bridge safety monitor...

AI Technical Summary

Problems solved by technology

[0003] The existing bridge safety monitoring and early warning system cannot provide technical support for the real-time and visualization of bridge safety monitoring and early warning. When the bridge undergoes unpredictable deformation and cracks under load, it cannot be repaired or evacuated in time, and It is impossible to use visualization to identify the damaged parts, which requires a lot of manpower and material resources for detection, which often delays the best time for maintenance. Therefore, a BIM-based bridge safety monitoring and early warning system is proposed
