In the following embodiments of the present invention, illustrated exemplified by studying and judging the security risk in subway work scene, therefore, mesh
Mark object is subway line,
Fig. 1 is the method flow schematic diagram that construction safety risk is studied and judged in the embodiment of the present application one；As shown in figure 1, it is wrapped
Include following steps S101-S107：
S101, three-dimensional GIS platform established based on OpenGL, three-dimensional scenic is established in three-dimensional GIS platform and in the three-dimensional
Subway line of the displaying with coordinate value and station point thereon in scene；
In the present embodiment, specifically using the satellite high definition image and DEM of subway line region as data medium, generation three
The three-dimensional slice of dimension ground scape, then issuing service is carried out to three-dimensional slice, after issuing service, obtained by three-dimensional GIS platform described in
Service, so as to show the three-dimensional scenic of subway line region in three-dimensional GIS platform and tool is shown in the three-dimensional scenic
There are coordinate value subway line and station point thereon.
In the present embodiment, the point data of subway line is converted to especially by by the line number evidence of subway line, then therefrom carry
The coordinate value of subway line and its website of getting on the bus is taken out, the coordinate value can be specifically latitude and longitude value.
Station Design axle net on S102, foundation subway line, and establish station agent structure BIM models, risk source BIM
Model, monitoring point BIM models, then by station agent structure BIM models, risk source BIM models, monitoring point BIM models with it is described
Axle net is bound；
In the present embodiment, setting, axle is online, to consider station agent structure BIM models, risk source BIM models, prison
Measuring point BIM models are in the online position of axle, can subsequently be bound.
In the present embodiment, station agent structure BIM models are such as related to the information such as the bracing members of station main body, wall.
In this implementation, risk source BIM models are such as related to the letter such as house, optical fiber, signal tower, sewage pipe, gas pipeline
Breath.
In the present embodiment, monitoring point BIM models ratio is such as relating to some monitoring points being arranged on around risk source.
In the present embodiment, station agent structure BIM models, risk source BIM models, monitoring can be specifically established based on axle net
Point BIM models, because the relative position of all BIM models and axle net is fixed all the time, in the binding between carrying out them
Relative position connection is created, accordingly even when axle net position is varied from, as long as axle net ensures the relative position with BIM models
Put, BIM models can changes with the change of axle net position.
S103, the axle net for having bound above-mentioned BIM models put in the coordinate system of the three-dimensional scenic；
In the present embodiment, if the coordinate system of the axle net is different from the coordinate system of the three-dimensional scenic, and the axle net
When the common point of the coordinate system of unknown, the described axle net of coordinate system and the coordinate system of the three-dimensional scenic is also unknown, according to setting
Angular view coordinate, axle net is put in three-dimensional scenic.
In the present embodiment, due in step s 102, due to the relative position of BIM models and axle net being had been carried out tying up
It is fixed, so, the axle net corresponding to selection during BIM models to be imported to three-dimensional GIS platform can be with automatic putting based on axle net

In the present embodiment, the monitor value of monitoring point is specially this observation of monitoring point, and this observation is included but not
It is limited to horizontal displacement value, sedimentation value, the axle power value for monitoring pipeline, bracing members, earth's surface etc..
When obtaining risk source and monitoring point, risk source information and monitoring point information, risk source information ratio can be read
Such as include risk source name, risk source numbering, risk class；Monitoring point information such as includes monitoring point numbering etc., while can
To obtain the recording of each risk source information of its monitoring, the record of each monitoring point information.
Wherein, in the case of there are a variety of numberings a monitoring point (i.e. a monitoring point monitors polytype situation),
A plurality of record is generated according to the multiple monitoring points numbering read.
It is whether identical as decision condition with risk source numbering using the first three items of monitoring point numbering in association, if prison
Measuring point numbering first three items are identical with risk source numbering, then this monitoring point is to monitor the risk source, new in data of monitoring point table
The risk source that an ID number records its ownership is built, while increases one newly in risk source data table and records monitoring point associated with it,
So as to complete associating for risk source and monitoring point.The record of Monitoring Data (or referred to as monitor value) is also based on monitoring point volume
Number recorded, thus can number according to monitoring point and then risk source, monitoring point are subjected to binding with Monitoring Data and associate.
S106, extract excavation models from the three-dimensional scenic for having put the axle net, and by the working procedure
Associated with the excavation models；
In the present embodiment, specifically, according to the foundation ditch standard paragraphs cutting depth in design drawing, width etc., and put
Good axle net, with reference to the location-based service in GIS spaces, is automatically positioned in three-dimensional scenic and draws out the two dimensional range of foundation ditch, profit
It is excavation models to stretch two-dimentional foundation ditch scope with excavation of foundation pit depth value.
S107, the BIM models of the excavation models and the monitor value are associated with according to practice of construction progress display
Between relation, to study and judge construction safety risk；
Specifically, by establishing interface with working procedure work breakdown structure (WBS), working procedure is called, is carrying out practice of construction
During progress is made a report on, working procedure corresponding to selection, so as to which practice of construction progress and working procedure work breakdown structure (WBS) be carried out
Binding.With making a report on for practice of construction progress, working procedure corresponding to activation and corresponding BIM models, including station body junction
Structure BIM models, risk source model, monitoring point model, correspondingly, monitoring frequency and monitor value the entering with construction speed of monitoring point
Row is also changing, and may thereby determine that BIM models and monitors the relation between value changes, further studies and judges construction safety risk,
And it can finally navigate to corresponding construction part.
