Application of 3D modeling software based on CnGIM_ma in engineering surveying

水电工程勘察中,传统的二维数据分析方法效率低、局限性强,不能满足现今社会发展要求。为应用三维地质模型技术实现地质信息从二维空间到三维空间的变革,解决传统二维数据分析方法的不足,以具体水电站工程可研阶段勘察为例,基于CnGIM_ma建模软件,以地质剖面、物探剖面、钻孔、平硐数据为基础,开展了三维地质模型建立及应用研究。结果表明:利用三维地质模型技术可以提高原始数据处理的效率及准确性,快速、及时地呈现地质信息并进行综合分析评价,为三维设计提供技术支撑,具有重要的实际应用价值。

In hydropower engineering survey,the traditional two-dimensional data analysis method is difficult to meet the requirements of modern social development for its low efficiency and strong limitations.In order to apply three-dimensional geological model technology to realize the transformation of geological information from two-dimensional space to three-dimensional space and overcome the shortcomings of traditional two-dimensional data analysis methods,taking the engineering investigation of a hydropower station in the feasibility stage as a studying case,by using CnGIM_ma modeling software and based on geological profile,geophysical profile,borehole and adit data of this project,the establishment and application of three-dimensional geological model were carried out.The results showed that 3D geological model technology can improve the efficiency and accuracy of original data processing,quickly and timely present geological information,comprehensively analyze and evaluate geological information,provide technical support for 3D designs and has important practical values.
