THE INFORMATION PROCESSING MODEL AND TECHNICAL METHOD FOR ENGINEERING-GEOLOGICAL WORK OF THE CHANGJIANG RIVER EMBANKMENT

The main engineering project of flood controlling in the middle and lower reaches of the Changjiang River implemented on the back levee of the Changjiang River.The Changjaing River embankment, a long course and a large project, has a mass of existing geological data.The hydrologic and geologic conditions for the embankment foundation are complex. Henceforth in the engineering-geological investigation work repairing and reinforcing the embankment, it is necessary to collect, store, index, analyse, count and maintain data as well as to transfer these data in order to synthesise and compile reports and maps at any moment.In flood season, the related data can be provided for inquiry and transfer of concerned files, or maps in decision making and used intaking measures dealing with an emergency. It increase the value in use and utilization of geological data, in the same way, it ensures the veracity, integrality and share of the imformation. Therefore, it is important to constitute reasonable Changjiang River embankment engineering geological information processing model and to get this technical method mature.
