Designing And Realization Of Dam System Layout Based On GIS

In last years, more and more silt dam that is most effectual project measure is being built, with plenty of work was done for improving circumstance of the Loess Plateau in china. The layout of dam system is base of dam system plan, it is very important for economizing investment. The traditional layout method cast a lot of time and labor, when analyzing on catchment's properties, such as measuring and calculating area, extracting ravine line and drawing section of ravine line. If the flood control operation is demanded, traditional method will be completed very difficultly. Because traditional layout method takes higher cost, it can't meet request of department of designing and examining. In these days, high-technology, like GIS, having been used in lots of trade of nature and society, it has become an important problem that improving dam system layout and manage efficiency and design result veracity, with a method combining GIS's spatial analysis and virtual reality function and traditional dam system layout theory and method. This paper expounded a dam system layout idea based GIS. It studied dam system layout on the Loess Plateau that technology-support is GIS, and core theory is dam system stabilization. In this system, computer simulated dam system layout model, and could dynamic analysis and get amount, type and composing of building, combining 3D visual modeling and Human-Computer interaction. This system that drastically changes dam system layout work, provides scientific, easy and visual method for dam system layout design and decision-making on the Loess Plateau, and improves dam system layout efficiency, and economizes investment.
