Referring to Fig. 2-Fig. 4, the railroad bridge construction project time management side based on 3dgis and engineering threedimensional model of the present invention
Method, comprises the following steps: three-dimensional scenic is set up, bridge work point model decomposes and the construction data importing, setting up X-Y scheme
Make a report on system, set up the construction data auditing system of X-Y scheme, set up actual progress data base, set up target advance data
Storehouse, carry out three-dimensional image progress based on progress data driving model and show, generate progress report and carry out progress early warning.Concrete step
Suddenly as follows:
1st, three-dimensional scenic is set up: the digital image data in rail track region is processed and generates orthography dom, by numeral
Altitude data process generate digital elevation model dem, then orthography is superimposed with digital elevation model render generate virtual
Three-dimensional scenic.
2nd, bridge work point model decomposes and imports: by engineering control decomposing, by bridge work point model be divided into pile foundation, cushion cap,
Pier shaft, beam section and beam block, import and are shown in 3dgis platform and manage, bridge work point model adopts parametric modeling mode,
Automatically extract parameter from two-dimensional design drawing, generate threedimensional model using the interface that 3ds max provides；From two-dimensional design drawing
In automatically extract parameter, carry out secondary development under autocad platform, according to professionally-designed chart lateral model, set up interpreting blueprints rule,
Interpreting blueprints rule according to definition is interpreted, with figure layer, color, line style as foundation, to annotation, component multistage in design drawing
Line, cross section structure parameter are refined, and extract design parameter.In order to show pier shaft progress, pier shaft needs by highly dividing further
Solution, typically can be decomposed by 3 meters one section, pile foundation, cushion cap, beam section, beam block etc. do not need to decompose further.Make bridge work
Point part is three-dimensional to import table, and including unit number definition, geographical coordinate calculates and attitude parameter calculates, and imports in table according to three-dimensional
Geographical coordinate and attitude parameter, realize the seamless spliced of bridge work point part and assembling.Unit number defines: its pile foundation,
Cushion cap, the numbering of pier shaft are made up of work vertex type, work point numbering, unit type, bridge pier numbering, element type, unit number, beam
Section, beam block number are made up of work vertex type, work point numbering, unit type, beam numbering, unit number, and such as numbering is 1-21-p-0-
Z-0, wherein 1 expression bridge, 21 represent work point numbering, and p represents bridge pier, and 0 represents bridge pier numbering, and z represents drilled pile, 0 expression stake
Numbering.
3rd, the construction data carrying out X-Y scheme is made a report on: the parameter automatically extracting in two-dimensional design drawing is stored in data
Storehouse, obtains work point parameter, the assembly providing and interface realize the quick of work point vector figure using openlayers from data base
Draw, render, roam and scale, click vector element carries out progress and makes a report on, and pile foundation, cushion cap, beam section and beam block progress are with completing
Represent with undone two states, pier shaft progress actually accomplishes height by input and represents.In order to ensure the verity of data, use
The progress data that family is made a report on need to audit ability input database by auditor, and usually unit in charge of construction's surveyor enters line number
According to making a report on, supervisor auditor is audited.
4th, carry out the construction data examination ＆ verification of X-Y scheme: the progress data that user makes a report on is audited, needs to audit
Data be highlighted on vectogram, by click on check the progress msg made a report on, underproof data is marked, moves back
Return something for repairs and change, if all qualified, enter next step, by data inputting actual progress data base.
5th, set up actual progress data base: in the progress data input database that examination ＆ verification is passed through, it is right to need before warehouse-in
Data carries out logical consistency inspection, and such as pier shaft does not complete, above beam section can not possibly complete.Data after warehouse-in can not be more
Change.
6th, set up target advance data base: by the target advance input database of work point, particularly as follows: using gunter drawing
Method is formulated work point and is applied group plan input database, when the plan initial time including each task and component and plan complete
Between, the planned start time of such as No. 19 pier pier shafts is August in 2016 20, and Projected completion time is September in 2016 20.
7th, carry out three-dimensional image progress based on progress data driving model to show: lookup acquisition work point one day from data base
Phase actual progress data and target advance data, calculate the completion statuses of work each component of point model according to progress data, according to
The color of each component of status modifier, realizes bridge construction three-dimensional image progress and shows.As completed use blueness represents, do not open
Begin represents with Lycoperdon polymorphum Vitt, actual progress exceedes target advance redness and represents, actual progress delayed target advance yellow represents.
8th, generate progress report: statistical query is carried out to progress data, day, week, month, year, Kai Lei branch can be extracted, divide
Item project data, generates progress report.As can be with statistical query currently all bridge work point drilled piles, cushion cap, pier shaft, beam etc.
Day, week, month, year, open tired quantity performed, volume residual etc..
9th, progress early warning: actual progress data and target advance data are analyzed, calculate advanced or delayed
Duration, formulate advanced warning grade, when exceeding definition grade, automatically send short messages to related personnel, carry out progress warning.As red in defined
Color, orange, yellow, blue level Four advanced warning grade, red delayed 60 days, orange delayed 40 days, delayed 20 days of yellow, blue delayed
10 days, when exceeding yellow advanced warning grade, automatically send short messages to related management personnel and reminded.
