Foundation design of large-scale and deep water caisson

Lu Qinfeng,Zhao Douhuan,Yang Jin

Strategic Study of CAE 2010, Volume 12, Issue 4,   Pages 9-13

Abstract: proposals are studied for the foundation type of the middle tower, especially the comparison between caissonThe caisson foundation is adopted because of its concise structural behavior, larger rigidity and simpler's dimension is 58 m×44 m with four circle chambers at corners, the total depth of the caissonThe bottom segment of the caisson adopts concrete caisson with steel hull, and its upper segment adoptsThe design of the caisson foundation will provided good experience for the future similar projects.
