| 摘 要： | 针对日照市城市可持续发展中面临的地质环境和地质资源问题，开展蓝色经济区城市三维地质结构调查。运用先进的勘察技术、地理信息系统技术、三维地质建模技术，开展城市三维地质结构填图，建立了日照市钻孔三维实体、第四系结构、基岩结构三维模型。通过数字曲面拟合和计算机图形学的方法，把空间分布不均匀、不连续、散乱的地质信息变成可视的、连续的、形象直观的三维地质模型，以三维图象的形式形象地表达了各种地质结构的真实形态、特征，圈定影响深基础开挖和地下空间利用的不良地质体范围，为日照市地下空间资源开发利用提供地质依据。

| Abstract: | Aiming at the problems of geological environment and geological resources faced in sustainable development in Rizhao city, three dimensional geological structure investigation of Rizhao Blue Economic Zone in Shandong province has been carried out. By using advanced investigation technology, geographic information system technology and 3D geological modeling technology, the urban 3D geological structure mapping has been carried out, and 3D models of borehole 3D entity, quaternary structure and bedrock structure in Rizhao city have been established. Through digital surface fitting method and computer graphics method, geological information with uneven, discontinuous and scattered spatial distribution has been transformed into a visual, continuous and intuitive threedimensional geological model. It will vividly expresses real shape and characteristics of various geological structures in the form of three dimensional images, and delineate the scope of adverse geological bodies affecting deep foundation excavation and underground space utilization. It will provide the basis of geological conditions for the development and utilization of underground space resources in Rizhao city. |
