Compared with prior art, the present invention has the following advantages:
1) the present invention is by setting up three-dimensional visualization model, shows the design idea of Tunnel Engineering designer more intuitively, improves construction accuracy rate and efficiency;
2) three-dimension animation technology is incorporated in emulation by the present invention, intuitively starting point is visualized as with data, electric power tunnel work progress Three-Dimensional Dynamic form is represented, embody the time of each operation in electric power tunnel work progress, space and logical relation, disclose the dynamic behaviour feature of system; Three-dimension animation technology fully exposes leak in design and defect, contributes to systems specialists and proposes fruitful opinions and suggestions, feed back Construction State in time, and can be used for the dynamic management of guiding construction process.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in detail.The present embodiment is implemented premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
A kind of based on digitized electric power tunnel construction control method, the method comprises the following steps:
1) set up tunnel three-dimensional visualization model according to design data, be specially:
Set up part model based on the tunnel segment structure in tunnel, equipment, affiliated facility or sectional model according to design data, carry out assembled according to the locating information of Tunnel Design axis or stretch, automatically generating whole tunnel three-dimensional model.
Shield structure (push pipe) tunnel set up and the three-dimensional model of affiliated facility thereof have following feature: have the advantages that to carry out assembling (or being stretched along axis by section) according to component; Have the advantages that constantly change with work progress; Have feature longer and shorter in z direction on x, y direction, namely model is long and narrow structure.
Except These characteristics, the three-dimensional model of shield structure (push pipe) tunnel and affiliated facility thereof also should adapt with digital Platform, and namely requirement can easily network be transmitted, and model file can not be too large.In addition model file should have certain versatility, is convenient to format conversion.
2) obtain current construction speed data, adopt three-dimension animation technology to carry out work progress dynamic simulation to tunnel three-dimensional visualization model, and recording simulation results;
Described construction speed data comprise Lining Ring number, the initial mileage of lining cutting, stop mileage and engineering time, and the mode of construction speed data acquisition comprises: from construction data-base, single obtains or batch obtains from standard format excel form.
Shield structure (item pipe) tunnel is finally assembled by section of jurisdiction (joint), if regard every endless tube sheet (joint) as a short broken line, whole piece tunnel can be regarded as and carried out matching approx formed by the set of one group of short broken line (broken line length is that a lining papers builds width).The design axis in tunnel is joined end to end by some dissimilar segment of curve and forms.In tunnel, each structure, equipment are also along axis arranged.The each structure in tunnel, equipment and affiliated facility can be determined jointly by axial location and cross section place.
In the design of shield structure (item pipe) Tunnel Engineering, the design axis (DTA) in tunnel is made up of horizontal curve and vertical curve.Horizontal curve refers to DTA projection of shape in the horizontal plane; Vertical curve refers to the fluctuating situation of DTA on longitudinal profile.Alignment elements then refers to the geometrical characteristic forming horizontal curve and vertical curve.Horizontal curve in tunnel generally comprises straight line, circular curve, adjustment curve three kinds.Wherein, adjustment curve is divided into again the gentle straight curve (starting point curvature is definite value) of straight slow curve (starting point curvature is zero).Vertical curve comprises straight line and circular curve two kinds.Therefore plane curve element can be divided into four kinds according to linear difference: straight line, circular curve, straight slow curve ease up straight curve.Between horizontal curve and vertical curve with plane mileage for contacting, its geometric description equation can be extracted according to the alignment elements of horizontal curve and vertical curve, and with the three-dimensional accurate coordinates of plane mileage for variable determination tunnel axis.
