Abstract:

Due to increased complexity of projects, an integrated information environment is needed. To demonstrate the capabilities of such a system, we choose an implementation in automated shield tunnelling. Automated shield tunnelling applications have increased in popularity due to the increased flexibility and construction safety. These automation machines have proven to be cost effective in tunnelling through congested areas, typical of large cities and metropolitan centers. The productivity of tunnelling conditions is directly related to the soil conditions in the site which impacts the total cost and schedule of the project. Therefore it is extremely advantageous to utilize an efficient method for storage, retrieval and manipulation of soil information. The storage of borelogs should also contain information on the geographic location of borelogs to allow the user to retrieve soil information related to all the borelogs in the vicinity of a construction project. Geographic Information Systems (GIS) can relate descriptive project information to graphical displays showing their geographical locations on digital maps on the computer screen. Since GISs currently available concentrate on planar/surface applications, there is a need to extend their utility to show the soil variations as a function of depth ( i.e. from a 2D to a 3D application). This paper describes a system that integrates a database for the storage of descriptive soil data, a GIS to relate this data to a display of corresponding locations of boreholes, and a module to interpolate between the soil borelogs to develop a three dimensional representation of the soil layers underlying the project site. The outcome of this project is particularly useful for Design-Build organizations where the utilization of a single database for analysis, design and construction planning is an important step towards design-construction integration.
