Design And Implementation Of3D Geological Modeling Based On GOCAD

With the fast development of national economic and hydropower construction,3D geological modeling are greatly demanded by various departments. How to make those data distributed in an efficient way has become the urgent issue of all construction sectors.In order to meet the requirements of urban construction sectors’ needs for basic geographical data, basic geological data and reconnaissance data, this paper choose GOCAD as software platform to develop3D geological modeling of one hydropower station. The thesis takes one hydropower station as an illustration, making use of the GOCAD software, the3D geo-modeling is built up. The modeling can show the geological structure of the underground information in vivid detail, which includes3D strata information, construction excavation,3D tunnel, faults, etc. It provides a kind of methods for personnel engaging in the engineering geologic quality assessment which help them analysis the engineering geologic phenomenon and master the structure regulation in rock and soil body, etc. The thesis mainly includes the following works:1. Based on the analyzing of current3D geological modeling system, this paper systemically summarized the system structures, technologies and main research issues of3D geo-modeling. The suitable geo-modeling system, the system structures&technologies, were then determined according to our needs after several comparations.2. The resolution of3D geo-modeling using GOCAD software was identified based on the characteristics of reconnaissance information systems, which should offer accurate, prompt, direct and wide information to meet the user’s needs, and the software’s characteristics of practicality, interaction, security and economy.3. Based on the considerations and methods above, the thesis take GOCAD as platform to develop3D geo-modeling of one hydropower station using DSI technology. The modeling has been employed in one hydropower station.
