低山丘陵地区市政道路的 BIM 正向设计

低山丘陵地区的市政道路设计不同于平原地区，存在高桥隧比、平纵线形受地形与造价限制等问题，还需要尽量减少对自然环境的生态影响。结合成都市东西城市轴线龙泉山段道路的设计方案，论述设计低山丘陵地区市政道路线形时的控制要点，并结合BIM应用在前期方案设计中对道路线形进行直观展示，以实现对项目功能与造价的合理控制。

BIM Forward Design of Municipal Roads in Low Mountain and Hilly Areas

The design of municipal roads in low-mountain and hilly areas is different from that in plain areas. There are the problems in the high proportion of bridges and tunnels, and the terrain and cost limits of horizontal and vertical alignment. At the same time, it is necessary to minimize the ecological impact on the natural environment. Combined with the design scheme for the roads in the section of Longquan Mountain in the east-west urban axis, the control essentials in the design of municipal road alignment in the low-mountain and hilly area are discussed. And combined with BIM application in the early scheme design, the road alignment is visually displayed so as to realize the reasonable control of project function and cost.
