Abstract
The Shanghai World Plaza is a multi-function building located in Shanghai Pudong New Development Area. It is a steel structure with thirty eight stories (199m) above the ground and three stories of basement. The excavation area of this building is 75m by 100m. The depth of the excavation is 16m to 18m (kernel part). The construction site is covered with soft soils up to a depth of 25m. Main streets, pipelines and existing buildings surround the site. The retaining structure employs a diaphragm with 1m in thickness, 30m in depth and 340m in total length. Three levels of H shaped steel supports are placed on 163 steel columns. De-watering of groundwater was applied during the excavation in order to decrease the hydraulic gradient and to improve the soils at the bottom of the excavation. Field monitoring includes 40 settlement/displacement points to cover main street pavements, pipelines and diaphragm units. Other items of monitoring include the excessive pore water pressure within the soils, multi-layer settlement, inclination of the retaining walls, lateral soil pressure, axial supporting force and, stresses within the diaphragm.
