公路地质BIM建模原理与应用初探

Preliminary Study on the Principle and Application of BIM Geological Modeling in Highway

传统的地质勘察是以点和线勘察为主。为了建立地质模型,则需对无勘察数据的区域进行插值。通过多种插值方法的对比分析,发现克里金法插值效果与实际地质趋势最接近。但因实际地质条件复杂,并不能完全依赖插值解决,应通过不同的剖面绘制地质分界线来补充勘察数据,剖面间用插值连接,生成三维地质模型。地质模型的应用价值很多,如直观反映地质信息、计算工程量、结构分析、优化构筑物设计等。

Traditional geological survey mainly focuses on dot and line. In order to establish geological model, interpolation is necessary in the areas lacking data. By analyzing and comparing various interpolation methods, Kriging interpolation method matches perfectly with the actual geological condition. However, the actual geological condition tends to be complicated, so only interpolation is not enough. In order to gain 3 D geological model, the geological data needs to be supplemented by geological profile and the interpolation connects separate profiles. The values of the 3 D geological model are numerous, for example, it reflects geological information directly,calculates engineering load, analyzes structure and updates the design of structures and so on.
