Application Study Of 3-D Technique In The Project Of Road Design Of Route

This article elaborated the importance of the road route plane, the longitudinal section, the cross section and the synthesis design in the road design. Thought traditional the two-dimensional location method has not been able to satisfy our country road construction the need. Already became one of influence road construction quality restriction factors. At present, the domestic and foreign universal acknowledgments is should use the three dimensional road design model to design the three dimensional road entity. Three dimensional design concept statement, Is a road design idea significant transformation, To improves the location quality, optimizes the road design very important function.But, the three dimensional animation technology realization method quite are now many, majority all exists realizes complex, the function is unitary, data exchange frequent and so on shortcomings, and pauses most in the static three dimensional stage, is not mature regarding the dynamic three dimensional technology.Stemming from above reason, this article from three dimensional animation realization method obtaining, thorough research three dimensional animation technology in location application.In the road design route even, vertical, horizontal and the comprehensive design is in the road design important design content, affects to the road operational performance, not the good synthesis design possibly can appear the line of sight not to be good, dark concave and so on driving hidden dangers, affects the traffic safety.Former even, vertical, horizontal and the comprehensive design all is, this method which according to the plane vertical surface coordination, the vertical surface square face coordination and the plane square face coordination carries on not only influence working efficiency, moreover only can be with the plane graph examination three-dimensional road, the existence limitation, simultaneously to designs personnel's experience to request high.In order to enhance the road route the design quality, promptly finds the problem in the design earlier period, takes the measure early, avoids using the two-dimensional design method to design the three dimensional road entity, improves the design quality, reduces the design cycle, in the road design should as soon as possible realize comprehensively, the integrated three dimensional location.Therefore, the three dimensional animation technology appeared in the location application and the popularization is extremely important. This article careful analysis at present domestic and foreign route three dimensional animation realization method, had thought designs the platform based on CARD/1 the three dimensional animation design is the realization three dimensional location good method.Its main merit is as follows:①The simulation effect foundation is the CARD/1 design data and the topographic diagram data, does not need to establish the data model, does not have any data exchange process, the guarantee design precision.②Through carries out the three dimensional animation to become the chart control file, the synchronized demonstration three dimensional animation, may carry on the apparent distance computation.③May adjust the direction of travel, the driving route, the driving speed, the line of sight altitude, the viewpoint altitude.④If to designs the achievement not to be unsatisfied, after carries on the revision design, does not need to do any work then after to carry out the three dimensional animation again to become the chart control file to obtain the revision three dimensional animation.⑤Only then realizes through the CARD/1 location software, does not need using 3DMAX, AUTOCAD and so on to design the software.Needs the essential data preparation using the CARD/1 location software realization three dimensional animation design, including the diffraction grating chart, the aerial torographic map data as well as the actual topographic diagram data processing method, the diffraction grating chart arrow quantification, meanwhile introduced needed to use this design software using the CARD/1 location software realization three dimensional animation to carry on the route the plane, the vertical surface and the cross section design, in which elaborated the CARD/1 cross section design and the method of exploitation with emphasis.May say is uses this software using the CARD/1 location software realization three dimensional animation design premise to carry on the road the location, like this only then can the true realization road integrated design, this also be the road designer initiates continuously.CARD/1 designs the platform internal development order collection development and the use is uses the CARD/1 location software realization three dimensional animation design the key to be at, this article has conducted the analysis research to the cross section development order function and the application method, introduced the CARD/1 location software in order to realize the three dimensional animation design to carry on the development the internal command collection and the application, including the definition model contact surface, the traffic lane, the contact surface bestows on the material quality and provides the path order.Introduced CARD/1 designs the platform three dimensional animation establishment document the establishment method.Manifested CARD/1 to design the platform fully the open procedure development thought, has conducted the re-development research to this procedure, and has carried on the application in the actual engineering project, to used around the three dimensional animation technology to carry on the various comparison.Using the CARD/1 design software realization three dimensional animation design, its merit is obvious, the shortcoming is may overcome.CARD/1 provides the operation and develops the platform is at present any kind of road route design software does not have, its trundle grows the procedure function is other road route design software is unable to have, the author to designs the software the development mentality to approve vigorously, and recommends vigorously, this also is CARD/1 realizes the high quality three dimensional animation intrinsic reason.About yingchengzi to songjianghe highway 12th design section engineering design project in the actual project application, because this project location plan choice and the even vertical surface target use was enormous to the project influence, therefore the three dimensional animation technology applied in this project quite is essential.Myself tie should the project concrete design work, used the CARD/1 location software to make the three dimensional animation in particular to this project in red deer ditch route plan, carried on the panoram inspection to the project, in satisfied the traffic safety under the premise, original location target suitable depression, both reduced to along the route the environment influence, and has saved the project construction cost, the true optimized design, and proposed in this foundation took refuge from danger the traffic lane, the climbing lane and so on the safety work measure, after the examination design proposal was reasonable.This article has analyzed the three dimensional location substitution two-dimensional design method reason from many angles, has analyzed the three dimensional location trend of development, believed, the three dimensional animation technology will certainly to substitute for traditional completely in the location application the two-dimensional location method.Is engaged in many year road reconnaissance design from the author the angle to come to see this kind of trend of development is quite obvious, and turns towards integrated the direction to develop.The author is engaged in many year location work, from applies each kind of location software the experience to look, thinks at present, realizes the route three dimensional animation design good method using the CARD/1 location software, is worth in a home more widespread promotion and the application.Uses CARD/1 to design the platform to be able to optimize the location, reduces the construction cost, improves the route even vertical surface coordination, and realization method simple feasible, is one kind is worth promoting to all newly built roads, in particular in the mountainous area road route design method.
