摘要:

为体现三维地质模型的准确性、完整性并反映地质条件的透明度对地质模型的实用价值,针对复杂的地质现象、稀疏的采样数据和繁琐的建模过程中影响地质模型的精度与透明化的关键因素,提出一种基于BIM与虚拟钻孔信息构建的三维透明化地质建模方法。该方法通过三维透明化地质模型梯级构建理念和地层层序建立方法,结合高精度感知技术和原始勘探钻孔数据提出了采集地层特征参数的方法; 同时引入虚拟钻孔并采用Delaunay三角剖分算法增加钻孔数据点密度,以勘探钻孔和其他原始资料为数据源,借助空间插值算法构建了虚拟钻孔空间位置与特征信息。结果表明:该方法基于BIM技术,采用“点-面-体”逐次递进构建地层,实现了自动构建三维透明化地质模型功能; 利用施工阶段地层暴露或局部详勘获取的地层信息,通过动态反馈实现对三维地质模型信息误差的修正,驱动三维地质模型动态重构,逐步梯次实现目标区域地质条件透明化,为地下工程精细化施工和信息化管理决策提供有益指导。

Abstract:

In order to demonstrate the practical value of the accuracy, completeness, and transparency of 3D geological model in reflecting geological conditions, a 3D transparent geological modeling method based on BIM and information construction of virtual boring holes was proposed to address the key factors that affect the accuracy and transparency of the geological model in complex geological phenomena, sparse sampling data, and tedious modeling processes. This method proposed a method for collecting geological characteristic parameters by combining the concept of 3D transparent geological model cascade construction and the method of establishing stratigraphic sequences, as well as high-precision perception technology and original exploration drilling data. At the same time, virtual drilling was introduced and Delaunay triangulation algorithm was used to increase the density of drilling data points. Exploration drilling and other raw data were used as data sources, and spatial interpolation algorithm was used to construct the spatial position and feature information of virtual drilling. The results show that this method is based on BIM technology and uses a “point-face-volume” progressive approach to construct geological layers, achieving the automatic construction of three-dimensional transparent geological models. By utilizing the geological information obtained from the exposed strata or local detailed survey during the construction phase, dynamic feedback is used to correct the errors in the three-dimensional geological model information, driving the dynamic reconstruction of the three-dimensional geological model and gradually achieving transparency of the geological conditions in the target area, which can provide useful guidance for the fine construction and information management decision-making of underground engineering.
