Design And Realization Of Tunnel CAD

After years of development,the current domestic road and bridge professional design software has been various,and be widely used in engineering practice,and achieved good economic results.All along,due to the few tunnel project,the researchers and inputs are not enough,so far there is no practical tunnel CAD for use.According to the tunnel engineering design work experience,taking the tunnel CAD system related technology,demand analysis,system design,verification for a more in-depth research work as the main line.In this thesis,We have made a thorough study on three related technologies of tunnel CAD system,NET API parametric drawing technology,tunnel horizontal and vertical section drawing and 3D tunnel modeling algorithm of core technology,based on conventional modern encryption technology of network encryption technology.For analysis of the system demand,this thesis starting directly from the actual demand of the tunnel design work,introduces the main contents of the tunnel design,summarized the overall design of tunnel,the structural design of tunnel foundation pit,the inside main structure design of tunnel,other special tunnel design,3D modeling of tunnel,tunnel design tools and system console etc.functional requirements.Based on the system requirement analysis,the architecture of tunnel CAD system: Vertical and horizontal design subsystem of tunnel,tunnel cross section design subsystem,tool collection system,3D tunnel modeling system andconsole subsystem 5 subsystems,a total of 46 functional modules.And realize the 46 functional modules of the 5 subsystems of planning,so as to make it a practical and useful tunnel CAD system software.After the system is implemented,the software test is carried out,in order to detect defects in the software and make continuous modifications and improvements.After the completion of the system test,and applied in the construction design of the 6 tunnels.The results show that the system greatly improves the production efficiency,saves a lot of manpower and material resources,and has obvious benefits.Finally,the thesis summarizes the writing,points out the shortcomings,and prospects the further development of the tunnel CAD system.
