RESEARCH INTO INTEGRATED DEVELOPMENT OF ENGINEERING GEOLOGICAL INFORMATION SYSTEM FOR THREE GORGES DAM

This paper analyzes the technical features of and the correlation among the three software system: the database managemnt system (DBMS), the geographic information system (GIS), and the computer-assisted design system (CAD) that are different from the classic "3S" technology. This integrated technology can be used to reveal the important role of the "3S" technology mentioned above in the integrated management of the spatial information for the Three Gorges dam, with the aid of the engineering geological information features of the Three Gorges dam. The present research results show that the secondary integration development of the DBMS, GIS and CAD with their higher ratios between price and performance can meet the demand for the capture, input, management and treatment of the engineering geological data with multi-dimension, multi-source, multi-volume and multi-variable. This integrated system developed with the "3S" technology provides us with the following functions: the fast capture and real-time update of the data, the integrated management of graphs and texts, and the computer-assisted map construction. Therefore, this integrated system provides us with a scientific method for the improvement to the engineering exploration and construction technology and for the reduction in the construction cycle.
