The BIM based monitoring and supporting axial force system includes an axial force monitoring module, an axial force calculation and processing module, a lightweight BIM image module, an intelligent early warning module and an end user. According to the BIMbased monitoring and supporting axial force system and method, a BIM information technology and equipment Internet of Things are used for completing a dynamic early warning of a subway construction visualization site, the structure is simple, the design is scientific and reasonable, conception is ingenious, the force and deformation of the axial force monitoring of a subway station can be accurately monitored in real time, and accurate positioning and real-time monitoring of the early warning can be achieved through the real-time visual monitoring of the end user to effectively avoid the construction risk. The BIM based monitoring and supporting axial force system and method are simple in structure, scientific and reasonable in design, ingenious in conception, and each axial force point can be monitored accurately in real time. When a value of a certain axial force point is higher than a threshold value, an alarm is given to the end user in time, the safety of construction is effectively improved, and the value of popularization and application is wide.

Description

technical field [0001] The invention belongs to the technical field of subway construction and relates to a supporting axial force, in particular to a BIM-based system and method for monitoring the supporting axial force of a subway open excavation foundation pit. Background technique [0002] There are a large number of axial force monitoring operations in the construction of open-cut subway stations, and the safety management pressure is high. The structure of the subway project is complex and the construction site is small. Manual monitoring of axial force is time-consuming and labor-intensive. Axial force monitoring of subway open cut stations has always been a difficult and important point in the process of rail transit construction. The traditional axial force monitoring method is inefficient, the labor cost is too high, and the steps are complicated, and there are many mechanical monitoring tasks. The on-site technicians cannot timely obtain the force changes of the a...

AI Technical Summary

Problems solved by technology

The traditional axial force monitoring method is inefficient, the labor cost is too high, and the steps are complicated, and there are many mechanical monitoring tasks. The on-site technicians cannot timely obtain the force changes of the axial force monitoring during the construction process, and thus cannot make correct judgments.

Effective rectification measures cannot be formulated in time for the potential safety hazards
