摘要
利用海量地质资料构建高精度三维地质模型,首先需要对建模区的地质资料进行规范化、标准化处理,而进行岩土体结构划分则是其首要环节。以成都市中心城区为例,在充分研究成都市中心城区基础地质、工程地质、水文地质资料和大量工勘资料的基础上,结合国家、行业和地方相关标准,建立了满足不同尺度、不同精度三维地质建模需要的岩土体结构分层方案。通过典型区域的三维地质模型建模示范应用,岩土体分层物理力学指标离散性分析和工程地质问题分析,可以看出该岩土体结构划分方案合理。研究成果对海量地质资料的标准化建库和三维地质模型建立,以及提高地质资料利用率等方面具有重要意义,对城市规划建设、重大工程选址和岩土工程勘察也具有一定的指导作用。
In order to construct 3D geological model by geological data,it is necessary to standardize the geological data in modeling area.The division of rock-soil mass structure is the first step.On the basis of fully studying the geological,engineering geological and hydrogeological data of the central urban area of Chengdu,combined with the relevant national,industrial and local standards,the layered scheme of rock-soil mass structures is established to meet the needs of 3D geological modeling with different scales and precision.Through the application of 3D geological modeling in typical areas,the discrete analysis of physical and mechanical indexes of rock-soil layers and the analysis of engineering and geology,the division scheme of rock-soil mass structure is reasonable.The research results are of great significance to the standardization of massive geological data,the establishment of 3D geological model,and the improvement of geological data utilization.It provides a certain reference in urban planning,engineering site selection and geotechnical engineering survey.
