Embodiment
As shown in Figure 1, a kind of Construction of Hydropower Engineering process visualization preview system, comprises 4 software modules such as construction speed module, digital terrain module, 3D MBM, visual simulative analysis module.
Present system hardware is made up of server end and local client, construction speed module, digital terrain module, 3D MBM, visual simulative analysis module are installed in system server, and local client is by the software module on networking operation server.What construction speed module, digital terrain module, 3D MBM, visual simulative analysis module adopted successively is Project Management Software, dimensional topography process software, 3D modeling software and simulation analysis software.
Described construction speed module is for working out hydropower project construction schedule, and described construction schedule mainly comprises construction task, duration information, Gantt chart, network chart etc.
Described digital terrain module is for building construction area original figure relief block, and described digital terrain module carries out excavation and filling process according to design profile line to original figure relief block.By a series of discrete point having 3 d space coordinate data of digital terrain block combiner, create construction area original figure relief block.Topographical surface adopts the TIN curved surface with three dimensions attribute to describe, and carries out foundation ditch in 3 d mode and slope excavating, levelling of the land, road fill, and is realized the excavation and filling process of digital terrain model by amendment triangulation network curved surface.
Digital terrain model is also known as digital elevation model.Namely, in a region, ground form is expressed with coordinate X, Y, Z of intensive relief block point.Digital terrain model is mainly used in describing surface irregularity situation, may be used for extracting various terrain parameter, as the gradient, slope aspect, roughness etc., and carries out the applied analysis such as flux-vector splitting, river basin authorities generation.Digital terrain model can have multiple expression, comprises grid, level line, the triangulation network etc.
Adopted the methods such as solid modelling, feature entity modeling, parameterized solid modeling to build the 3D models such as buildings, preparation of construction, material facility by 3D MBM.
(1), solid modelling: concrete gravity dam, earth and rockfill dam adopt body modeling method.Auxiliary construction plant, concrete macrotype preparation of construction etc. are general not as the engineering object of statistics and analysis, there is no fixing size and position, mainly emphasize expressive force and appearance, therefore mostly adopt simplified model or three-dimensional material that directly assembly system is built-in.
(2), feature entity modeling: cavern's class buildingss such as diversion tunnel, flood discharging tunnel, emptying tunnel, form of fracture is circular, gateway opening shape, and general structure divides oblique straight section, bending section, transition etc., adopts feature entity modeling.
