Design And Development Of The Safety Evaluation Decision Support System For The Concrete Dam

With the implementation and deepening constantly of the China's strategy to develop its western regions, and the development thoroughly of the water resource, the key water control project facilities of our country are increasing constantly. Up till now, our country has already built up about 87000 all kinds of reservoirs, large-scale key water control project among them take concrete dam as the core more. In recent years, because of each kind of reason, quite a part of dams have been in danger, so the dam security problem appears especially importantly. So, it is necessary to set up safety evaluation DSS of concrete dam, offering strong decision support to safe appraiser. It is the element task of setting up safety evaluation DSS of concrete dam to manage the basic database management subsystem of the observation data out of shape of the dam.In this article, on a large number of foundations of studying the current situation both at home and abroad, we carry on demand analysis to safety evaluation DSS of concrete dam, and we have made the overall goal of the system, then designed the overall frame of safety evaluation DSS of concrete dam.Secondly, based on the actual project of the Yellow River Long Yang Xia dam deformation of power station, we have carried on systematic analysis to the monitoring data of dam. At the same time, the basic data database is developed with the normal method of database designing with working out a set of feasible database building the warehouse standard.At last, the object-oriented software was selected in the basic database management subsystem. The series of software planning steps were carried out before the basic database management subsystem was set up. The author established the basic database management subsystem by using Visual C++ and ADO database visiting technology and it has realized to manage and analyze the information of power station.The basic database management subsystem will reasonably and effectively manage the monitoring data out of shape of the Long Yang Xia power station. It has practicably offered facilitating servers to the dam supervise unit for information processing.
