BIM+GIS技术在复杂山区公路选线中的应用研究

复杂山区公路路线设计方案受地形、地质条件影响较大。如何有效利用多源地理信息数据对关键节点进行合理布设是确保设计质量、控制工程造价的关键。文中以实际山区公路工程为例,提出基于BIM+GIS技术的地形、地质、环保选线方法。研究结果表明:①基于BIM+GIS三维地理信息模型可以更直观地审视路线方案,更准确地进行工程量统计校核;②BIM+GIS模型融入地形、地质、环保等控制因素可以更有效地进行设计方案优化比选,减少设计变更、提高设计质量。

Research on BIM+GIS Technology Application in Route Selection of Complex Mountain Highway

The design of highway route in complex mountainous areas is greatly affected by topography,landform and geological conditions.How to effectively use multi-source geographic information data to lay out key nodes rationally is the key to ensure design quality and control project cost.In this paper,the terrain,geology and environmental protection route selection method based on BIM+GIS technology is proposed based on the actual mountain highway project as an example.The research results show that:①Based on BIM+GIS 3D geographic information model,the route scheme can be more intuitively examined and the quantity of engineering statistics can be checked more accurately;②BIM+GIS model can integrate terrain,geology,environmental protection and other control factors to optimize and select design schemes more effectively,and reduce design changes and improve design quality.
