基于BIM技术的复杂岩溶地区三维地质建模方法研究与应用

3D Geological Modeling Method and Its Application in Complex Karst Area Based on BIM Technology

由于传统地质建模无法直接应用指导设计、施工过程,且在复杂岩溶地区中,缺乏三维地质建模的方法。在南宁国际空港工程中,为突破传统地质建模方法在复杂岩溶地区表达不清、实用性不高的弊端,通过Revit平台,结合钻探、RTK等探测技术,在多源数据相互印证下,提出复杂岩溶地区三维地质建模方法,该方法有效结合BIM技术与多种勘测技术,简化复杂岩溶地区地质表达方式,对岩溶地基后续施工处理提供有效的模型数据支撑。

The traditional geological modeling cannot be directly applied to guide the design and construction process.What’s worse,there is a lack of 3D geological modeling method in complex karst areas.To tackle the problems of unclear expression and low practicability of traditional geological modeling methods in complex karst areas,a three-dimensional geological modeling method is proposed through the Revit platform,combined with drilling,RTK and other detection technologies and under the mutual confirmation of multi-source data in Nanning International Airport Project.By effectively combining BIM technology with various survey technologies,this method simplifies the geological expression in complex karst areas,provides effective model data support for the subsequent construction of karst foundation.
