Design Of A Platform About Arch Dam Analysis Software

Arch dams are well known for their fine shape,excellent mechanical properties,reasonable structure,and economic cost.Considering the different stress conditions and structure of the arch dam are quite complex,the design procedures are also a complicated work.The design of arch dams is generally completed by using professional arch dam design software both inside and outside China currently.Even if the professional and technical personnel would to face a lot of difficulties by using these professional arch dam design software.There are many 300 meter-high level arch dams that are building or would build in the southwest of China,Such as Jinping level one arch dam,Xiluodu arch dam,Baihetan arch dam,Dagangshan arch dam and so on.These projects are located in the mountains of western China,the geological and climatic conditions are complex,as well as the high level of dam and large scale of reservoirs.Considering the mentioned factors above and the lack of guidance and discipline norms,the design of these arch dams is extremely difficult.It is difficult to analyze the stress of the arch dam by using the traditional arch dam design software,not to mention to solve the solution of arch dam optimization problem.Besides,the optimization under dynamic loading is especially difficult.This paper conforms to the need of super high arch dam construction in China,and develop a section containing the arch beam method of stress analysis and design procedures,arch dam finite element modeling dam stress analysis program.This arch dam design and analysis system software assembled the functions of 3D design of arch dam,calculation and analysis of stress,drawings output and calculation reports output.The software is called DamMP arch dam design and analysis system software.DamMP arch dam design and analysis system software is based on the secondary development of AutoCAD software.This software uses the meta-element to record the modeling information,making the software operation more intuitive and simple.In the design of arch dam system,it provides the function of finite element analysis and the calculation of arch-beam loading method,which is convenient for the preliminary selection of dam and stress analysis.This software is based on digital design concept BIM,the BIM method of arch dam design is put forward.The BIM method is adopted in the model center database and parameterization to form a system integrating design,analysis and plotting.In the system function realization,the system has the function of extensible template library,the establishment of a parametric modeling system and a unified graphics database,providing a quick means for the threedimensional modeling.
