摘要： 基于钻孔勘探、标准贯入、地形测量等多源异构岩土工程勘察资料，研究了岩土工程勘察场地的数据预处理、立体空间集成建模与可视化信息管理方法，开发了相应的软件系统，实现了地形、建筑物、钻孔、地层、地下水等空间对象的三维集成建模、真实感可视化、剖切分析及勘察成果的信息查询与更新，形成了岩土工程三维勘察报告新模式.经多个岩土工程实际项目的应用与验证表明:采用所提出的三维建模技术与可视化方法，可自动建立岩土工程场地的立体空间三维集成模型，对岩土工程勘察领域的三维信息化建设具有较高的应用价值.

Abstract: Based on several kinds of geotechnical engineering information obtained from multiple sources and different structures， such as drilling hole detection， standard penetration test， topographic surveying etc.， a series of specific methods for data preprocessing， integral modeling， 3D visualization and information management of the engineering sites were intensively inverstigated. Based on these methods， a software was developed， by which the stereo space of a geotechnical engineering site， including spatial objects such as topography， buildings， boreholes， stratum， groundwater etc.， can be integrally modeled and visualized with threedimensional models. These 3D models can facilitate functions such as attribute query， information updating and section analysis. The 3D integral modeling software was proposed as a new pattern of geotechnical engineering report beyond traditional 2D report. The software has been applied to several geotechnical projects， whose results demonstrate that the stereo space model of a geotechnical engineering site can be automatically and conveniently reconstructed. The 3D integral modeling and visualization methodology presented contribute a lot to 3D information technology development of geotechnical engineering.

Key words: digital city, geotechnical engineering, 3D geological modeling, integral modeling, 3D visualization, spatial information management
