基于 GIS-BIM 技术的山地城市长大通道选线方案及空间协同论证研究

山地城市长大通道具有地形条件复杂、里程长、控制因素多、工程投资大的特征。在国土空间规划“三区三线”划定落地的背景下,通道选线阶段应提前做好与“三区三线”的协同对接,集约利用土地等资源。针对山地城市长大通道的特征,分析线路设计方法与原则。以重庆中心城区—綦万快速通道工程为例,运用三维GIS技术建立基于大范围地形数据的基础模型,对路线方案进行三维可视化模拟分析,进行山地城市长大通道选线及空间协同论证实例分析。

Demonstration and Research on Route Selection Scheme and Spatial Collaboration of Long Passageway in Mountain City Based on GIS-BIM Technology

The long passageway in mountain city has the characteristics of complex terrain conditions, long mileage, many control factors and large engineering investment. In the context of the implementation of the "three regions and three lines" in the territorial spatial planning, the route selection stage should be well coordinated with the "three regions and three lines" in advance, and the intensive use of land and other resources. Aiming at the characteristics of long passageway in mountain city, the method and principle of route design are analyzed. Taking Chongqing Central City - Qiwan Express Passage Project as an example, 3D GIS technology is used to establish a basic model based on a wide range of terrain data, the 3D visualization simulation analysis of route scheme is carried out, and the demonstration example of route selection and spatial collaboration of long passageway in mountain city is analyzed.
