基于BIM技术的泵闸工程三维协同集成化设计方案研究

在泵闸工程多专业设计进程中,BIM三维协同技术是否优于传统二维协同设计,以及BIM集成化设计方案如何实现,是决定水利工程BIM技术推广应用亟需解决的问题。在二维设计串行工作方式的基础上,通过建立分解并行系数、校订并行系数和延滞系数三参数,综合反映协同任务并行程度。并行进程的量化分析表明:在中小型泵闸工程中,应用BIM三维协同技术较传统二维协同设计可提高设计效率约10%;在三维协同设计平台上,同步实现了设计阶段建模、协同、碰撞、图纸、报表等模块,完成数字一体化设计与交付,建立了BIM集成化设计方案的体系框架。BIM三维协同集成化设计可成为提升工程建设整体效率与设计质量的重要途径。

BIM technology-based 3-D collaborative integrated design scheme of pump-sluice project

During the process of the design of pump-sluice project with several specialities， whether the BIM 3-D collaborative technology is superior to the conventional 2-D collaborative design and how to realize the BIM integrated design are the problems urgently to be solved for dominating the popularization and application of BIM technology in the construction of water resources project. Based on the serial working mode of 2D design， the parallel degree of collaborative task is comprehensively reflected through establishing the three parameters， i.e. the decomposed parallel coefficient， the revised parallel coefficient and delayed coefficient. The quantitative analysis of the parallel process shows that in the small and medium-sized pump-sluice projects， the design efficiency can be raised by about 10% from the application of the BIM 3-D collaborative technology， if compared with that from the 2-D collaborative design； from which the modules in the design stage， such as modeling， collaborating， collision， drawing， reporting， etc.， are synchronizedly realized on the 3-D collaborative design platform， and then the digital integration design is completed and the system framework for the BIM integrated design scheme is established as well. The BIM 3-D collaborative and integrated design can become an important way to enhance the integral efficiency and design quality of engineering construction.
