| Abstract: | CAD is used to perform the calculating and drawing jobs of the parabolic variable-thickness double-curved arch dam of Nanzhang Xiakou hydropower project, such as the calculation of the arc length and the thickness and area of the arch rings, the volume of the dam etc., and the drawing of the arch ring plan, the arbitrary oblique profile, the twisted cross-section, the elevational drawing, the twisted joint line, the intersection points of bracket or gallery with the body of dam etc., when a bit of chord length of arch ring is needed to be increase in construction, the measure that how to keep invariable shape of the arch dam is considered especially. |
