Shield tunneling machine risk source crossing three-dimensional simulation and monitoring system based on BIM and GIS

Abstract

The invention relates to a shield tunneling machine risk source crossing three-dimensional simulation and monitoring system based on BIM and GIS. The system comprises a supervision platform which is used for fusing the model data of at least one risk sub-source and the real-time geographic information space data of the surrounding environment of the risk sub-source, wherein the model data comprises deformation data and static data, and the deformation data is collected by a laser scanning monitoring platform when the laser scanning monitoring platform monitors at least one risk sub-source in the crossing process of the shield tunneling machine. The supervision platform comprises a BIM sub-module and a GIS sub-module, wherein the BIM sub-module can acquire the deformation data under the condition that the GIS acquires the real-time geographic information spatial data and generate a comparison result based on comparison between the deformation data and the static data so that the supervision platform can dynamically manage and control the risk sub-source.

Description

technical field [0001] The invention relates to the field, in particular to a three-dimensional simulation and monitoring system for shield machine risk source crossing based on BIM and GIS. Background technique [0002] With the increase of urban subway construction density, the construction risks are also increasing. Newly built subway lines not only need to consider crossing existing buildings and structures, but also cross various operating lines (railway, highway, expressway, subway, etc.), which greatly increases the safety risk of construction. At present, the crossing risk of subway construction still relies on manual monitoring, especially for crossing highways, it is necessary to manually monitor the road surface, and passing vehicles bring great safety hazards to monitoring personnel; secondly, for the current crossing risk The management and control of the system is mainly based on two-dimensional data sources, which lacks an intuitive experience of the traversa...

Newly built subway lines not only need to consider crossing existing buildings and structures, but also cross various operating lines (railways, highways, expressways, subways, etc.), which greatly increases the safety risk of construction

At present, the crossing risk of subway construction still relies on manual monitoring, especially for the situation of crossing highways, it is necessary to manually monitor the road surface, and passing vehicles bring great safety hazards to monitoring personnel; secondly, for the current crossing risk The management and control of the system is mainly based on two-dimensional data sources, which lacks an intuitive experience of the traversal process, and due to various factors, the monitoring data cannot be collected, and real-time dynamic control of the traversal process cannot be realized.
