三维地质模型在泰安市地下空间开发中的应用

摘要

Nowadays,with the rapid process of urbanization,development and utilization of urban underground space has become the important tool of expanding building space capacity,relieving the jamming situation and en-hancing the environment quality.To deepen the recognition of Tai'an urban underground space and fully utilize the potential reserve space resource,through collecting drilling logging,geological maps and topographical maps,with the help of mapGIS 3D modeling software,3D geological model of Tai'an city has been set up.Geological informa-tion,such as rock and soil in engineering projects can be expressed in an intuitive way.It will provide reliable geo-logic bases for the development of urban underground space in Tai'an city.%在城市化进程不断加快的今天，城市地下空间开发利用已经成为提高城市容量、缓解交通、改善环境的重要手段。为全面深化对泰安城市地下空间的认识，有效挖掘城市后备空间资源的巨大潜力，通过综合集成钻孔编录、地质图件和数字地形图等多源地学数据，借助MapGIS三维地质建模软件，初步建立起泰安城市三维地质模型，以直观的方式表达工程岩土体空间分布等地质信息，为更好地保护利用泰安市地下空间提供地质依据。
