The three-dimensional numerical simulation of logarithmic spiral double curved arch dam

This paper studies logarithmic spiral double curved arch dam, and carries out analysis on the bodily form of the logarithmic spiral double curved arch dam, based on the arch dam stress analysis and construction lofting, and builds three-dimensional mathematical model, with the help of C⁺⁺ program language, automatically generates the three-dimensional model of the logarithmic spiral double curved arch dam with AutoCAD and divides the form into rectangular meshes. The three-dimensional curved surface is smooth, the rectangular meshes are evenly distributed, and reliable and accurate evidence has been provided for further structural and fluid analysis of the logarithmic spiral double curved arch dam.
