A three-dimensional simulation and monitoring system for shield machine risk source crossing based on bim and gis

Abstract

The invention relates to a BIM and GIS-based three-dimensional simulation and monitoring system for shield machine risk source crossing, including: a monitoring platform for fusing at least one risk sub-source model data and real-time geographic information spatial data of its surrounding environment; The model data includes deformation data and static data, wherein the deformation data is collected when the laser scanning monitoring platform monitors the at least one risk sub-source during the shield machine crossing process; the supervision platform includes a BIM sub-module and a GIS A submodule, wherein the BIM submodule can acquire the deformed data when the GIS acquires real-time geographic information spatial data, and compare the deformed data with the static data to generate a comparison result for The supervision platform can dynamically manage and control the risk sub-sources.

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.
