Deep Pit Foundation Steel Sheet Pile Supporting Scheme of the 274# Pile Cap for Super Large Bridge over the Coastal Expressway and the North Jiangsu Irrigation Canal

The results of considering the path effect and without considering the path effect computed by MIDAS/Civil are different, while the path effect can reflect the real stress of system in construction, but the deformation can not meet the construction standard. So we eliminate the stress of system and deformation accumulation in construction by changing the process of construction and using the hydraulic jack.
