Abstract:The Xiangjiaba open caissons group is part of the diversion works for Xiangjiaba Hydropower Station,and it is an important part of the main structure on the left bank. It consists of ten open caissons groups with size of 23 m×17 m. The maximum sinking depth is 60 m. The caissons must penetrate into strong permeable layers including sandy gravel layer,sandy layer and sandy gravel layer with collapsed stones,and embed into fine sandstone layer. The caisson construction is tremendous difficult in the world. According to special hydrogeological conditions,the rational caisson sinking sequences and caisson sinking technique are determined,and the caissons group sinking is completed successfully. A series of construction methods for caisson sinking are summarized.
