Through introduction to application practice of coordinate setting in concrete engineering, this paper makes a summary of general idea of curved bridge measurement in the area with complicated landform and works out the general program used for coordinate setting of rail-road curved bridge.

Then, a general program is worked out.

In this thesis, a conception of building a general program of earthquake disaster prevention and mitigation information system has been proposed from the angle of standardization and generalization, based on the summary of recent years researches on the information system and the analysis of commonness between several systems.
