Bentley-based 3D Parametric Design System for Gravity Dam
Based on Bentley platform design software Microstation,this paper conducts secondary development to study the three-dimensional parametric design system of gravity dam.The concept of"template"and"skeleton"is established to realize the functions of section design,anti-sliding stability calculation,dam body stress calculation,limit state calculation,finite element analysis,barrage layout,parametric modeling,automatic statistics of engineering quantities and three-dimensional assisted drawing in an integrated system.It has important reference significance and practical value to change the traditional design mode,improve the quality and efficiency of design,and promote the digital process of engineering design.
