Key Laboratory of Geotechnical and Underground Engineering of Ministry of EducationTongji UniversityShanghai200092 China 2. Department of Geotechnical EngineeringTongji UniversityShanghai200092China) Abstract After a comprehensive review on the exploitation of information technology in geotechnical engineering and underground engineeringa concept of digital underground space and engineering(DUSE) is proposed. The objectives of DUSE are strategically targeted to provide a way to obtain and organize information about underground space and engineering as follows(1) a framework in which to publish information (2) a set of standards about data (2) new software and services to process useful information out of these data and (4) new visualization tools to display all relevant information. Thena theoretical framework of DUSEwhich describes the system architecture of DUSE from the viewpoint of engineeringinformationservices and software system are put forward. Thusa taxonomy of all the data in the system is defined. Modeling of 3D space geometrical objects is divided into three categorieswhich are geological modelingpipeline modeling and underground structure modeling. Accordinglythe modeling methods of each categor
