Design and analysis of retaining structure for deep excavation of Banghua Global Plaza in Guangzhou

By introducing the design of retaining structure for deep excavation of Banghua Global Plaza in Guangzhou, some methods for designing retaining structure which consists of piles in row and soil anchors with ajacent foundation pit are analyzed. The finite element program Midas GTS is used to analyze the internal force and deformation of the double-row piles with cables. The calculated results and the monitoring data are compared. The proposed design method can be used for reference by similar projects.
