BIM技术在公路地质勘察中的应用

Application of BIM Technology in Highway Geological Survey

以南川隧道为例,采用BIM技术,融合地质调绘、勘探、地质剖面等多源地质信息数据构建三维地质模型,快速生成构造物三维模型,实现公路BIM模型融入三维地质勘察信息,全方位展现公路地质信息,弥补了公路工程建设BIM应用的短板。结果表明,采用BIM技术实现三维地质可视化成果与公路专业进行协同工作,可以全方位、立体展现构筑物场地地质环境,更加准确把握地质风险,为公路建设的顺利进行提供技术保障。

Taking Nanchuan Tunnel as an example,BIM technology is used to integrate multi-source geological information data such as geological mapping,exploration,and geological profile to build a three-dimensional geological model.BIM Technology could quickly generate a three-dimensional model of structures,integrate the highway BIM model into three-dimensional geological survey information,and comprehensively display highway geological information,making up for the shortcomings of BIM application in highway engineering construction.The results show that the collaborative work between 3D geological visualization results and highway specialty could be realized based on BIM technology,and the geological environment of the structure site could be displayed comprehensively and stereoscopically.Geological risks could be identified more accurately,and technical support could be provided for the progress of highway construction.
