3D Finite Element Analysis on DongQing CFRD

Abstract:

As a competitive dam style and full of life-force, the concrete- faced rockfill dam (CFRD) is widely used in China in recent years. Experts in China pointed out that “Extra high CFRD generally means those CFRDs with their heights higher than 150 m ” However, the history of construction and design of extra high CFRD is short and some problems during the construction of Extra high CFRD is still need to be explored. Therefore, stress and deformation characteristic of DongQing extra high CFRD was analyzed by 3D finite element method and some beneficial reference was obtained. Firstly, the advanced 3D mesh generation procedure written by Fortran language was used to form the finite element mesh which contained not only the dam with large amount of vertical joins and perimeric joints, but also the rock foundation and surrounding mountains. Moreover, the layer by layer construction procedure of dam was detail considered during 3D mesh generation. Since the node number of 3D mesh is still larger, large scales equations solving method-element by element method and others efficient measures were adopted. As the results, the computer calculation time decreased from former 48 hours to 20 minutes. According to the calculation results, the design scheme of DongQing CFRD was finally optimized.
