【摘要】：當(dāng)前,基于城市道路信息模型構(gòu)建來實現(xiàn)對道路設(shè)計和施工過程的三維動態(tài)化還處于探索階段。提出了將BIM技術(shù)應(yīng)用于城市道路建設(shè)中,構(gòu)建基于道路設(shè)計施工的信息模型理念,利用BIM構(gòu)建了基于道路線性選擇的指標(biāo)參數(shù),同時引入Civil 3D軟件構(gòu)建三維虛擬模型,提取相應(yīng)的模型參數(shù),并利用建立的指標(biāo)評價體系進行了不同線性選型的方案對比,獲得最佳的線路設(shè)計效果。研究結(jié)果表明:采用BIM技術(shù)下的三維地形曲面獲得的模型結(jié)構(gòu)更為直觀,模型指標(biāo)層次分析更具優(yōu)勢,模型參數(shù)的結(jié)果計算更精確;通過融合Civil 3D和BIM技術(shù),將信息模型參數(shù)應(yīng)用于道路綜合設(shè)計、施工模擬和道路景觀設(shè)計、行駛舒適度體驗等道路工程項目全周期都具備了很強的適應(yīng)性�？僧a(chǎn)生良好的經(jīng)濟效益。
[Abstract]:At present, it is still in the exploration stage to realize 3D dynamic road design and construction based on urban road information model. This paper puts forward the idea of constructing information model based on road design and construction by applying BIM technology to urban road construction, constructs index parameters based on road linear selection by using BIM, and introduces Civil 3D software to construct 3D virtual model. The model parameters are extracted and the different linear selection schemes are compared by using the established index evaluation system to obtain the best route design effect. The results show that the model structure obtained by using 3D terrain surface based on BIM technology is more intuitive, the hierarchical analysis of model indexes has more advantages, and the results of model parameters are more accurate. The application of information model parameters in road comprehensive design, construction simulation, road landscape design, driving comfort experience and other road engineering projects has a strong adaptability. It can produce good economic benefit.
