BIM技术在山地城市大型市政工程中的应用——新燕尾山隧道工程BIM应用

Application of BIM Technology in Large-scale Municipal Engineering in Mountainous Area

新燕尾山隧道工程地处重庆巴南区,项目呈东西走向,为重庆南部片区重要主干路。项目全长6.96 km,由一个菱形简易立交、两个全互通立交、一个超长穿山隧道组成。项目穿越城市建成区与风景区,工程受周围环境影响大,山地地理区位明显。为提高设计效率,保证工程质量,提出"C+DY+R+I"的BIM设计路线,并借助二次开发,实现数据在BIM平台中的互通。通过对可视化编程、椭球比七参数的迭代公式推导、参数化动画建模等新技术与BIM的结合,提出了一整套适用于山地城市大型市政工程的BIM解决方案,为BIM技术在该领域的发展提供新思路。

New Yanweishan Tunnel Project is located in Banan District of Chongqing with an east-west trend,and is an important main road in the south of Chongqing.The total length of the project is 6.96 km.The project is composed of a diamond simple interchange,two full interchanges and a super-long mountain tunnel.The project passes through the built areas and scenic spots of the city.The project is greatly influenced by the surrounding environment.The mountain geographical location is obvious.In order to improve the design efficiency and guarantee the engineering quality,the BIM design route of"C+DY+R+I"is proposed.And the data interworking is realized in the BIM platform with the help of secondary development.Through the combination of new technologies such as visual programming,iterative formula derivation of seven parameters of ellipsoid ratio and parametric animation modeling with BIM,a complete set of BIM solutions suitable for large-scale municipal projects in mountainous cities is proposed,which provides a new way for the development of BIM technology in this field.
